Pregnancy Patient Education
Pregnancy is measured in three time periods, or trimesters, starting with the first day of the last menstrual period. During each trimester, specific fetal developments occur and the full term pregnancy is considered 40 weeks.
The information contained below is for general patient education. Ask your OB/Gyn about specific developmental milestones and symptoms you experience in each trimester.
The First Trimester (0-13 weeks)
- Most important for fetal development
- Baby’s organs and structures form
- Majority of birth defects at this time as do miscarriages
Maternal changes during the first trimester include:
- Breast tenderness
- Frequent urination
- Emotional fluctuation of extremes and sensitivity
The Second Trimester (14-26 weeks)
- Fetal organs further develop
- Movement first felt at 16-20 weeks
Maternal changes during the second trimester include:
- Energy returns and increases
- Nausea greatly diminishes
- Constipation and abdominal discomfort
- Back pains
- Leg cramps
The Third Trimester (27-40 weeks)
- Baby starts descending downwards towards the birth canal
- Baby rotates so that the head is the closest part in the birth canal
Maternal changes during the second trimester include:
- Varicose veins
- Difficulty sleeping/insomnia
- Shortness of breath
- Urinary Incontinence
- Swelling with some Fluid retention
- Mild, irregular cramps
Doctors Who Are Part of the Pregnancy Team
Choosing the person who will deliver your child is a personal decision and there are various types of healthcare workers who can be involved in your delivery. Listed in this patient education guide are the doctors most commonly called on by expecting mothers.
- Obstetrician -A physician specializing in all aspects of pregnancy, labor, delivery and after-care of the pregnant patient. This doctor also diagnoses and treats conditions associated with pregnancies as well as maintaining the diagnosis and treatment of a normal pregnancy.
- Midwife -A healthcare provider who cares for the expectant mother during the pregnancy as well as the labor, delivery and postpartum periods.
- Perinatologist -An obstetrical subspecialist who deals with the care of the expectant mother and fetus in high-risk pregnancies or when associated medical problems exist.
- Nutritionist -A professional who formulates diet plans for both the healthy and compromised individuals as well as advising which vitamins and supplements would promote good health.
- Doula -Professional offering both physical and emotional support as well as information to the pregnant mother-to-be. She is a patient advocate, answering any questions regarding the birthing process and assists in forming a birthing plan. The doula also presents when labor starts to aid in breathing, massage and pain relief methods.
- General Practitioner -A physician who treats both acute and chronic conditions for patients of all ages and also provides preventive care. In some geographical areas, the general practitioner or family doctor can care for the expectant mother and also perform a simple delivery.
How to Prepare for Your Pregnancy
Our pregnancy education guide gives you an overview of what you can expect and how to prepare in each of the trimesters throughout your pregnancy.
How to Prepare for the First Trimester
During the first trimester, preparation focuses on getting you ready to give birth in nine months.
- Diet - Because the baby is forming now, it is crucial to eat properly with balanced meals. Avoid alcoholic beverages and smoking. Eat plenty of vegetables and fruits and take a multivitamin daily.
- Choosing a Healthcare Provider - Have a complete physical examination and consult with an obstetrician or midwife as soon as pregnancy is suspected.
- Exercise - Routine exercise decreases stress, improves mental focus and improves your physical stamina to prepare for labor in the future. Exercising three times a week has been shown to help babies in their neurological development as well. Avoid contact sports or activities that can cause potential risk to bodily harm (e,g. skiing). Dance and low-impact or isometric exercises as well as swimming and brisk walking are great forms of exercise. Tip- wear a good support bra to avoid discomfort.
- Diagnostic tests will be performed at specific time intervals. Sonogram (ultrasound) preparation for the test consists of having a full bladder – 8 glasses of water are consumed. (refer to diagnostic tests in Expect section)
How to Prepare for the Second Trimester
During the second trimester, preparation focuses on the birth and future care of the baby.
- Making the Announcement - Some expectant mothers wait until after the first trimester to share their happy news with family and friends. If you are one of those, it is now time to spread the word and announce your pregnancy. This will help with any support you may need.
- Location of Delivery - If you are planning on having a delivery at a hospital, tour the hospitals that you are considering. Make sure that it is a hospital that meets your requirements or is in alignment with your expectations. Also make sure that the hospital is one that your physician is affiliated with.
If you are planning on delivery at a birthing center, tour this facility. Find out where you would be transferred if a more specialized delivery becomes warranted. Again, if you are planning a home delivery, consider what facility you would be transferred to in an emergency. Also, it is now time to start amassing items you would need for the home delivery.
- Birthing Plan - Formulate a scheme which addresses pain medication and one in keeping with the program you have chosen (e.g. Lamaze, Bradley)
- Birthing Classes - Can be given in groups or privately and may be located at home or the location where delivery is contemplated. There are several types reflecting particular methods such as Lamaze or Bradley.
- Childcare Purchases - Fun preparation starts too! It’s time to purchase the crib and all additional things that the baby will need like the car seat, layette, carriage and stroller. While it is much easier to construct the crib before the third trimester, some may choose to wait. Most stores will allow you to purchase these items and have them sent upon delivery of the baby.
- Doula - Decide whether you would like a doula to assist with birthing plans and the labor process. If so, now is the time to secure one.
- Preparing the Breasts - If you choose to breast?feed the baby after delivery, it is time to prepare the nipples. Each day, rub them for a minute sporadically with a wet washcloth to desensitize them.
How to Prepare for the Third Trimester
As one approaches the home stretch, preparation centers on the actual delivery event and post-delivery actions.
- Pediatrician Selection - The pediatrician is chosen so that medical care can be given to the baby upon birth and securing continued health. The selection process will include interviewing several physicians in this specialty to ensure that it is a provider that you feel comfortable with and one who is in alignment with your preferences or thoughts.
- Address Book - Make note of the address book or directory on your phone including emails. Add any additional people or data so that it is easy to contact those you would like to inform about your happy event. Also add any services to the directory that you may need to contact after delivery as well.
- Childcare - Consider who will be caring for the baby upon delivery. If a baby nurse will be hired for the care upon arriving home, interview and hire this nurse at this point. Also address the issue of who will be watching the baby if you are returning to work outside the home. Discuss care with family members and interview childcare facilities prior to delivery. Don’t wait until you are confronted with this issue.
- Names for the Baby - Choosing a name for the baby should not be done hastily. After all, your child will be carrying this name around for a long time. Consider the first with the last name as well as the monogram. Make sure that it is not something that the child will be ridiculed for in the future. (Also consider that while a nickname may seem cute on a baby, it may not be so for an adult.)
- Announcement Cards - If you plan on sending out cards through either the post office or an e-card service, select the ones that you like now. It will be one less item on your task list later when time is at a premium.
- Camera - If you are planning on taking video or photos of the birthing experience and the new baby, make sure that your camera is charged and you have spare batteries.
- CD Player/iPod with Charger - Playing soothing music during labor enhances the birthing experience and makes labor contractions easier to tolerate. Take the music with you.
- Labor and Delivery Bag - Inside this bag, you will have a change of clothes for yourself and an outfit for the baby to wear when you leave the hospital. Include your personal hygiene products, robe, slippers and hair products. Also include items that you may want to use in labor (e.g. tennis ball for back massages, socks during labor, etc.)
- Baby Care Items - Having diapers and bottles on hand are good preparation. If you are not using disposable diapers, and plan on a diaper service, have them lined up. If you plan on breastfeeding, getting a pump is a good idea.

Common Tests or Labs Throughout Your Pregnancy
During each obstetrical visit throughout the pregnancy, the medical assistant or nurse will measure weight and blood pressure while sitting. The urine is also tested each time for glucose, protein and blood.
The fundal height, or height of the uterus, is measured from the top of the pubic bone to the top of the uterus. At 20 weeks the fundal height will reach the level of the umbilicus and from then until 35 weeks, there is a consistent relationship between the pregnancy length and fundal height (exceptions include multiple gestation i.e. twins or fibroids). Read more about common tests in this patient education guide.
COMMON TESTS IN THE FIRST TRIMESTER
|Blood Type and Rh||If Rh Negative, will test Father for Rh to ensure compatibility with baby||After a tourniquet is applied to the upper arm, the puncture site of skin is swabbed with alcohol and a needle punctures the skin, entering a vein. Blood is drawn into a syringe for analysis. The tourniquet is then removed and a pressure bandage is applied||Rh Positive is less risk|
|Complete Blood Count
|Checks for anemia
|After a tourniquet is applied to the upper arm, the puncture site of skin is swabbed with alcohol and a needle punctures the skin, entering a vein. Blood is drawn into a syringe for analysis. The tourniquet is then removed and a pressure bandage is applied||WBC=4.5-11RBC=4.1-5.1Hemoglobin
|Screen for Rubella,hepatitis B, syphilis and HIV||Checks for immunity||After a tourniquet is applied to the upper arm, the puncture site of skin is swabbed with alcohol and a needle punctures the skin, entering a vein. Blood is drawn into a syringe for analysis. The tourniquet is then removed and a pressure bandage is applied||IgG antibodies <7IU/mLHIV negative, hep.neg.VDRL negative
|Tay-Sachs||Checks for risk of the disease||Hexosaminidase A: 7.2-9.8 U/LTotal Hexosaminidase=9.8-15.9 U/L|
|Sickle Cell Anemia||Checks for risk of the disease||Hemoglobin A (not S)|
|Ultrasound||Confirms age of fetusVisualizes structural abnormalities in uterus and fetus||After lying down on the table, the technician/doctor places clear water-based gel on your tummy and pelvic area. A hand-held probe is then moved back and forth over the area, transmitting sound waves. The echoes of these waves creates an image on a computer monitorSometimes a transvaginal ultrasound is performed. Here, you lie on the exam table with knees bent and feet in stirrups. A covered probe is lubricated and placed in the vagina. The probe emits sound waves and the echoes create an image on a computer monitor.||Fetal and uterine size matches the dateNo structural problems seen|
|Urine||Presence of glucose, protein, blood||Urine is placed in a cup for analysis. The technician dips a special paper into the urine for analysis with color changes||Glucose, protein and blood should be absent in a normal specimen|
|Chorionic Villus Sampling||Screens baby for genetic defects at 10-12 weeks||An ultrasound locates the uterine position and placental position in the uterus. The vulva, vagina cervix and abdomen are wiped with an antiseptic wash.A thin plastic tube is inserted through the vagina and cervix to reach the placenta, guided with ultrasound and a small sample of tissue is removed.In the transabdominal approach, a needle is inserted through the abdomen and uterus into the placenta. Tissue is withdrawn into a syringe||The DNA of the baby is analyzed.It fails to detect neural tube defect or Rh incompatibility and an amniocentesis is needed if this is a concern.A normal test means there are no genetic defects.|
COMMON TESTS IN THE SECOND TRIMESTER
|Blood for genetic markers (done in 15-18th wk):
|Abnormal markers indicate the need for additional testing (usually a sonogram and possibly an amnio-centesis)Abnormal levels suggest:
Abnormal levels are linked to increased risk of chromosomal abnormality
|Alpha-Fetoprotein Screening (AFP)Normal range is .5-2.0 or 2.t MoM
Human Chorionic Gonadotropin (hCG)
The hCG levels increase during the pregnancy
At 13-16 wks=13,300-
Estriol & Inhibin
Estriol and inhibin is elevated more than twice the median value in normal pregnancies with genetic problems
|Amniocentesis||Done during the 16-18th gestational week to do the following:-Rule out any genetic disorder-Determine sex of baby
-Rule out Tay-Sachs in baby
|The doctor inserts a needle through the abdomen and into the uterine sac to remove a small amount of amniotic fluid. The needle is withdrawn and pressure is applied to the puncture siteThe test is usually done with ultrasound guidance to locate the amniotic fluid.||XX for girlXY for boy
Hexosaminidase A is absent
|Urine Test||Looks for glucose, protein and blood in the urine||Urine is deposited into a cup. The technician then dips a special paper into the urine which changes color for presence of these three substances.||Normal result is when these are absent|
|One-Hour Glucose Tolerance Test||Rules out Diabetes||You are given a cup of a 50 gm. sugar solution (orange or cola flavored) to drink. After one hour, blood is drawn and analyzed for sugar level.||Less than 140 mg/dL is normal.|
COMMON TESTS IN THE THIRD TRIMESTER
|Group B Streptococcus Screening||B Strep is associated with-Mental retardation-Fatality
|Swabs of the vagina and rectum are taken at 35-37 weeks to screen for presence of group B strep.||Negative presence of bacteria|
|Non-Stress Test||Indicated in high-risk pregnancies as:
||Fetal monitor is strapped across the mother’s abdomen with the device over the region of the fetal heart and a tracing is obtained of the fetal heart rate over time. Takes about 20 min.||Normal fetal heart rate is 120-140 beats/minute.Dips (decelerations) or accelerations beyond 140 is not seen|
|Contraction Stress Test||Predicts how the baby will cope to labor stress||The fetal monitor is strapped across the mother’s abdomen. She is then asked to stimulate the nipples to stimulate contractions or pitocin is given intravenously to create contractions.The fetal heart rate is then measured in response to the contractions.||Normal fetal heart rate is 120-140 beats/minute.Dips (decelerations) or accelerations beyond 140 is not seenWhen decelerations are seen in conjunction to the time of the contractions, it can suggest fetal head compressions.|
|Biophysical Profile||Gives a more accurate assessment of baby wellness||Most often done between 38-42 wks of pregnancy.Combines a non-stress test with an ultrasound||Rating of 0-2 (with 2 normal) is given for each of the following, with a score of ten as the best:-Muscle tone-Heart rate
-Amniotic fluid levels
A total score under 6 is abnormal and calls for delivery.
|Electronic Fetal Heart Monitoring||Tests fetal heart rate||A fetal doppler is placed on the mother’s abdomen over the fetal heart site||Regular pattern with 120-140 beats/min.|
|Pelvic Digital Examination||Assess any dilatation or thinning of the cervix and where the position of the fetal head is located in conjunction to the birth canal.Performed during the last 4 weeks of pregnancy||The patient bends her knees with her legs abducted and feet on the bed or in “frog-leg” position. The examiner gently parts the vaginal labia and inserts two fingers into the vagina and palpates the cervix to assess effacement (thinning of the cervix) and dilatation, estimated by the number of fingers that would span the opening.(For example, when the cervix is 3-4 cm dilated, 2-3 fingers would span the opening. When 10 cm. occurs, the opening is equivalent to five fingers.)||Effacement is the thinning out of the cervix in labor which goes from uneffaced at 0% to 100% effaced in normal labor.Dilatation goes from closed to 10 centimeters in normal labor|
Delivering Your Baby
When it comes to delivery, there are many different variables that can effect the birth. Some methods and treatments are optional, and some will become a necessity as your labor progresses. Read more in this patient education guide.
How it works
|Induction||Occasionally an enema is all that is needed to stimulate labor.More commonly evoked by IV infusion of pitocin to bring on regular contractions.After labor has commenced, an internal electrode may be inserted on the fetal head for a more accurate reading by rupturing membranes.|
|Episiotomy||Incision through vaginal wall and perineum, made when:
After delivery the incision is sutured (which heals better than a ragged tear that needs sewing)
|Spontaneous||Natural labor with rhythmic contractions and progression of the baby through the birth canal and delivered without instruments or prompting.|
|Forceps||Metal instrument with tongs and spoon-shaped edges molded to fit around the baby’s head.Forceps are used to:
|Vacuum Extraction||Device with cone-shaped synthetic, pliable suction cup which is placed over the baby’s head and attached to a pump, creating vacuum which has measured pressure applied. This enables the physician to hold the baby in place with each push, barring the baby from receding between contractions.|
|Caesarean Section||This is an operative delivery with an incision (either horizontal or vertical) made between the umbilicus and pubic bone, and carried down to the uterus, which is incised above the lower uterine segment. The baby is delivered within 5 minutes and the placenta is then manually removed. The remainder of the 45-60 minutes entails sewing the various layers to restore normal tissue integrity.Indications include:
There are two reasons why one would opt for anesthesia to be given.
In the first scenario, a patient may not be knowledgeable in deep breathing or natural birthing techniques that lessen pain or the patient may find it inadequate for the amount of pain that she is perceiving.
In the second case, anesthesia techniques are induced in order to relax the patient and the muscles so that delivery may be more easily affected.
How it works
|Local Anesthetic||Medication injected subcutaneously to numb a specific area prior to episiotomy or for mending a tissue tear in the perineum. It does not alter contraction pain.|
|Cervical Block||Local anesthetic injected into the cervix at four quadrants to lessen the pain associated with dilation and effacement of the cervix.|
|Pudendal Block||Local anesthetic is injected into the vaginal wall to numb the tissue between vagina and anus. Given in advanced labor and is effective in 10-20 minutes|
|Epidural Block||After lying or sitting on your side with back curved outward, a local anesthetic is injected to numb the lower back at the site of planned epidural needle entry.Medication is injected into the epidural space surrounding the spinal cord and becomes effective in 10 minutes. Sensory function is numbed while often retaining motor skills.|
|Spinal Block||Used in conjunction with instrument delivery. You sit or lie on your side and medication is injected with a spinal needle into the sac of fluid below the spinal cord, effective within minutes.|
|General Anesthesia (inhalation gases)||Administered by the anesthesiologist, this is a gas that is passed through a special machine and dosage regulated. Because it can sedate the baby, this is given when immediate sedation is needed as in imminent Caesarean section for fetal distress.|
