There can be misconceptions about what is ok to do during pregnancy. It’s commonly known to try to eat healthy while avoiding certain foods, exercise, and take your prenatal multivitamins, but other things may surprise you.

Before your little bundle of joy arrives, you’re responsible for helping them grow in a nurturing, healthy environment.

This list of pregnancy do’s, and don’ts can illuminate what you should worry about — and what you shouldn’t fret over.

1. Do take a multivitamin

Eating a balanced diet that’s rich in vitamins and minerals is the best way to provide your body with all of the healthy nutrients it needs to support a growing baby. A healthy diet alone, however, may not be enough for pregnancy.

Prenatal vitamins contain higher levels of certain nutrients that expectant mothers require at higher doses, such as:

  • folic acid
  • calcium
  • iron

These vitamins assist with proper development of the fetus and help prevent birth defects. Your doctor can help you find a multivitamin or a series of vitamins that are best for you.

A multivitamin will usually include DHA, EPA, or both. These are omega-3 fats that are important for your baby’s proper brain development.

Don’t take more than one dose of multivitamins, though. Some vitamins in higher amounts can be harmful to the baby.

2. Do get lots of sleep

Changing hormone levels, anticipation, and anxiety can make sleep elusive during your 9 months of pregnancy. Pregnancy is demanding, especially in the final trimester, and you’ll need your sleep.

Take a quick snooze if you feel tired and schedule naps whenever you can. Set bedtimes and stick to them.

Aim for 7-9 hours of shut-eye each night. Fatigue is a sign that your body needs more rest, so give yourself all the sleep you can.

3. Do work out

Gone are the days of pregnant women avoiding lifting a finger during their pregnancies: We now know that exercise is good for mama and baby.

In fact, regular exercise may help you combat many of the issues that arise during pregnancy, including:

  • insomnia
  • muscle pain
  • excessive weight gain
  • mood problems

If you regularly exercised before you became pregnant, keep it up. Talk with your doctor about any adjustments you should make to your routine, especially as you move into your second and third trimesters.

If you didn’t exercise regularly before you found out you were expecting, ask your doctor about incorporating a fitness routine into your day. They can guide you into a program that’s safe and comfortable for you and your growing baby.

4. Do eat seafood

Seafood is loaded with vitamins and minerals, such as heart-healthy omega-3 fatty acids, zinc, and iron. These are all important for both mom and baby. But undercooked or raw seafood can cause some problems.

Seafood may carry harmful bacteria and viruses, which are eliminated when thoroughly cooked. Also, pregnant women should avoid raw fish and fish that may contain high levels of mercury.

Examples of fish containing high levels of mercury include:

  • shark
  • swordfish
  • tilefish
  • king mackerel

Eat a variety of seafood so you don’t have a concentration of minerals from one type of fish. Eat no more than 12 ounces of fish per week.

5. Do have sex

Sex during pregnancy is fine, as long as you don’t have a complicating factor such as placenta previa or another type of high-risk pregnancy.

Sex is safe with your partner right up until your water breaks. If you have discomfort you may have to try new positions. Talk with your doctor if you have any questions about the safety of intercourse during your pregnancy.

6. Do practice yoga

You should avoid Bikram or hot yoga, but other yoga modalities are fine when you’re expecting. Seek out prenatal or gentle yoga classes that are designed for mothers-to-be. Instructors in these classes will know which poses are best and which you should avoid.

If you weren’t doing yoga before you became pregnant, talk with your doctor before signing up for a class. While it’s possible you can start, it’s best to go over the risks and concerns with your doctor.

7. Do get a flu shot

Pregnant women can and should get a flu vaccine as long as you don’t have a contraindication as noted by the manufacturer.

The injection isn’t a live virus. You cannot get the flu from the flu vaccine. If you were to contract influenza during your pregnancy, the risk of severe side effects is greater than in women of the same age who aren’t pregnant.

The vaccine will protect you as well as your developing fetus.

8. Do gain weight smartly

The “eat for two” advice to expecting mothers isn’t a license to eat whatever you’d like. Instead, women need to be strategic about what they eat and how much.

Gaining a lot of weight during pregnancy may do more harm to your baby than good. During your first trimester, you only need about 100 extra calories a day to support your growing fetus.

By your third trimester, that additional calorie number is closer to 300 to 500 per day.

9. Do visit your dentist

Trips to the dentist’s office were avoided for decades for fear that an oral cleaning might cause bacteria to spread and lead to an infection. Now we know that’s just not the case.

In fact, the American College of Obstetricians and Gynecologists recommends that expectant mothers have a routine oral health assessment while pregnant, along with regular dental cleanings. Be sure to tell your dentist that you’re pregnant.

10. Don’t smoke

Babies born to women who smoke during pregnancy are more likely to have a lower birth weight and are at a greater risk for learning disabilities than children born to nonsmoking mothers.

Additionally, children born to women who smoke are more likely to try smoking at a younger age and become regular smokers earlier, due to physiologic nicotine addiction.

11. Don’t drink alcohol

Alcohol may greatly impact your baby’s development. People who drink alcohol while pregnant could deliver a baby with fetal alcohol syndrome (FAS).

Symptoms of FAS include:

  • low birth weight
  • learning disabilities
  • behavior problems
  • lagging patterns in terms of growth and development milestones

Even small amounts of alcohol can be a problem. There appears to be no safe level of alcohol intake in pregnancy.

If you need help stopping drinking while you’re pregnant, talk with your doctor as soon as possible. The sooner you get help, the healthier your baby is likely to be.

12. Don’t eat raw meat

Raw and undercooked meat and eggs carry the risk of foodborne illness, such as listeriosis and toxoplasmosis. Food poisoning is also a possibility.

These conditions can cause serious, life-threatening illnesses that could lead to severe birth defects and even miscarriage. Make sure all eggs and meat that you eat while pregnant are well-cooked.

13. Don’t eat deli meat

Deli meats — including hot dogs, sausages, smoked salmon, and other cured meats — can cause foodborne illness, such as listeriosis and toxoplasmosis.

Meats that are sliced have far more surface area for bacterial growth. Thoroughly cooking these processed proteins well reduces your risk.

It’s also important to eat pasteurized (not raw) milk and cheese. Always wash produce to help eliminate harmful bacteria.

14. Don’t eat unpasteurized milk products

Calcium is very important for growing babies, but moms have to be careful how they get their calcium from dairy.

Raw milk isn’t recommended for expecting mothers since it’s unpasteurized. This means it hasn’t been heated to kill bacteria that could make you ill.

Specifically, raw milk may contain the bacteria Listeria. It can lead to illness, miscarriage, or even life-threatening consequences.

15. Don’t sit in a hot tub or sauna

Though relaxing, the high-heat environment of hot tubs, Jacuzzis, and saunas may be too dangerous for expecting mothers.

In fact, research suggests that using one of these during your first trimester may double your risk of miscarriage. Soaking in hot water can raise body temperature and this causes problems with the baby including increasing the risk of birth defects.

16. Don’t drink a lot of caffeine

Caffeine can travel through the placenta and increase your baby’s heart rate.

Current research suggests that women can safely consume a cup or two of coffee each day, but forego downing a triple-shot latte while you’re carrying.

17. Don’t clean the cat’s litter box

Pet your furry friend all you like and wash your hands afterward — but don’t clean a cat’s litter box.

Feline waste is filled with millions of bacteria and parasites. One in particular,Toxoplasma gondii, is particularly dangerous to expecting mothers.

If you contract it, you may never know until you begin having complications with your pregnancy. A miscarriage or stillbirth is possible. Babies who contract this parasite may face serious health problems, including seizures and mental disabilities.
