What do I need to know about pregnancy? A normal pregnancy lasts about 40 weeks. The first trimester lasts from your last period through the 12th week of pregnancy. The second trimester lasts from the 13th week of your pregnancy through the 23rd week. The third trimester lasts from your 24th week of pregnancy until your baby is born. If you know the date of your last period, your healthcare provider can estimate your due date. You may give birth to your baby any time from 37 weeks to 2 weeks after your due date.
What is prenatal care? Prenatal care is a series of visits with your healthcare provider throughout your pregnancy. Prenatal care can help prevent problems during pregnancy and childbirth. At each prenatal visit, your healthcare provider will weigh you and check your blood pressure. Your healthcare provider will also check your baby's heartbeat and growth. You may also need the following at some visits:
A pelvic exam allows your healthcare provider to see your cervix (the bottom part of your uterus). Your healthcare provider uses a speculum to gently open your vagina. He will check the size and shape of your uterus.
Blood tests may be done to check for gestational diabetes and anemia (low iron level). You may need other blood tests, such as blood type, Rh factor, or tests to check for birth defects.
A fetal ultrasound shows pictures of your baby inside your uterus. It shows your baby's development. The movement and position of your baby can also be seen. Your healthcare provider may be able to tell you what your baby's gender is during the ultrasound.
What can I do to have a healthy pregnancy?
Eat a variety of healthy foods. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy foods, beans, lean meats, and fish. Drink liquids as directed. Ask how much liquid to drink each day and which liquids are best for you. Limit caffeine to less than 200 milligrams each day. Limit your intake of fish to 2 servings each week. Choose fish low in mercury such as canned light tuna, shrimp, crab, salmon, cod, or tilapia. Do not eat fish high in mercury such as swordfish, tilefish, king mackerel, and shark.
Take prenatal vitamins as directed. Your need for certain vitamins and minerals, such as folic acid, increases during pregnancy. Prenatal vitamins provide some of the extra vitamins and minerals you need. Prenatal vitamins may also help to decrease the risk of certain birth defects.
Ask how much weight you should gain during your pregnancy. Too much or too little weight gain can be unhealthy for you and your baby.
Talk to your healthcare provider about exercise. Moderate exercise can help you stay fit. Your healthcare provider will help you plan an exercise program that is safe for you during pregnancy.
Do not smoke. If you smoke, it is never too late to quit. Smoking increases your risk of a miscarriage and other health problems during your pregnancy. Smoking can cause your baby to be born too early or weigh less at birth. Ask your healthcare provider for information if you need help quitting.
Do not drink alcohol. Alcohol passes from your body to your baby through the placenta. It can affect your baby's brain development and cause fetal alcohol syndrome (FAS). FAS is a group of conditions that causes mental, behavior, and growth problems.
Talk to your healthcare provider before you take any medicines. Many medicines may harm your baby if you take them when you are pregnant. Do not take any medicines, vitamins, herbs, or supplements without first talking to your healthcare provider. Never use illegal or street drugs (such as marijuana or cocaine) while you are pregnant.
What body changes may happen during my pregnancy?
Breast changes you will experience include tenderness and tingling during the early part of your pregnancy. Your breasts will become larger. You may need to use a support bra. You may see a thin, yellow fluid, called colostrum, leak from your nipples during the second trimester. Colostrum is a liquid that changes to milk about 3 days after you give birth.
Skin changes and stretch marks may occur during your pregnancy. You may have red marks, called stretch marks, on your skin. Stretch marks will usually fade after pregnancy. Use lotion if your skin is dry and itchy. The skin on your face, around your nipples, and below your belly button may darken. Most of the time, your skin will return to its normal color after your baby is born.
Morning sickness is nausea and vomiting that can happen at any time of day. Avoid fatty and spicy foods. Eat small meals throughout the day instead of large meals. Ginger may help to decrease nausea. Ask your healthcare provider about other ways of decreasing nausea and vomiting.
Heartburn may be caused by changes in your hormones during pregnancy. Your growing uterus may also push your stomach upward and force stomach acid to back up into your esophagus. Eat 4 or 5 small meals each day instead of large meals. Avoid spicy foods. Avoid eating right before bedtime.
Constipation may develop during your pregnancy. To treat constipation, eat foods high in fiber such as fiber cereals, beans, fruits, vegetables, whole-grain breads, and prune juice. Get regular exercise and drink plenty of water. Your healthcare provider may also suggest a fiber supplement to soften your bowel movements. Talk to your healthcare provider before you use any medicines to decrease constipation.
Hemorrhoids are enlarged veins in the rectal area. They may cause pain, itching, and bright red bleeding from your rectum. To decrease your risk of hemorrhoids, prevent constipation and do not strain to have a bowel movement. If you have hemorrhoids, soak in a tub of warm water to ease discomfort. Ask your healthcare provider how you can treat hemorrhoids.
Leg cramps and swelling may be caused by low calcium levels or the added weight of pregnancy. Raise your legs above the level of your heart to decrease swelling. During a leg cramp, stretch or massage the muscle that has the cramp. Heat may help decrease pain and muscle spasms. Apply heat on your muscle for 20 to 30 minutes every 2 hours for as many days as directed.
Back pain may occur as your baby grows. Do not stand for long periods of time or lift heavy items. Use good posture while you stand, squat, or bend. Wear low-heeled shoes with good support. Rest may also help to relieve back pain. Ask your healthcare provider about exercises you can do to strengthen your back muscles.
What are some safety tips during pregnancy?
Avoid hot tubs and saunas. Do not use a hot tub or sauna while you are pregnant, especially during your first trimester. Hot tubs and saunas may raise your baby's temperature and increase the risk of birth defects.
Avoid toxoplasmosis. This is an infection caused by eating raw meat or being around infected cat feces. It can cause birth defects, miscarriages, and other problems. Wash your hands after you touch raw meat. Make sure any meat is well-cooked before you eat it. Avoid raw eggs and unpasteurized milk. Use gloves or ask someone else to clean your cat's litter box while you are pregnant.
Ask your healthcare provider about travel. The most comfortable time to travel is during the second trimester. Ask your healthcare provider if you can travel after 36 weeks. You may not be able to travel in an airplane after 36 weeks. He may also recommend that you avoid long road trips.
