Pregnancy at 11 to 14 Weeks

Medically reviewed by Drugs.com. Last updated on May 1, 2023.

You are now at the end of your first trimester and entering your second trimester. Morning sickness usually goes away by this time. You may have other symptoms such as fatigue, frequent urination, and headaches. You may have gained 2 to 4 pounds by now.

DISCHARGE INSTRUCTIONS:

Return to the emergency department if:

You have pain or cramping in your abdomen or low back.
You have heavy vaginal bleeding or clotting.
You pass material that looks like tissue or large clots. Collect the material and bring it with you.

Call your doctor or obstetrician if:

You cannot keep food or drinks down, and you are losing weight.
You have light bleeding.
You have chills or a fever.
You have vaginal itching, burning, or pain.
You have yellow, green, white, or foul-smelling vaginal discharge.
You have pain or burning when you urinate, less urine than usual, or pink or bloody urine.
You have questions or concerns about your condition or care.

How to care for yourself at this stage of your pregnancy:

Get plenty of rest. You may feel more tired than normal. You may need to take naps or go to bed earlier.
Manage nausea and vomiting. 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.
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, 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.
Do not smoke. 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.

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.

Changes happening with your baby:

Your baby has fully formed fingernails and toenails. Your baby's heartbeat can now be heard. Ask your healthcare provider if you can listen to your baby's heartbeat. By week 14, your baby is over 4 inches long from the top of the head to the rump (baby's bottom). Your baby weighs over 3 ounces.

Prenatal care:

Prenatal care is a series of visits with your healthcare provider throughout your pregnancy. During the first 28 weeks of your pregnancy, you will see your healthcare provider 1 time each month. Prenatal care can help prevent problems during pregnancy and childbirth. Your healthcare provider will check your blood pressure and weight. Your baby's heart rate will also be checked. 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 will use a speculum to open your vagina. He or she will check the size and shape of your uterus.
Blood tests may be done to check for any of the following:
- Gestational diabetes or anemia (low iron level)
- Blood type or Rh factor, or certain birth defects
- Immunity to certain diseases, such as chickenpox or rubella
- An infection, such as a sexually transmitted infection, HIV, or hepatitis B
Hepatitis B may need to be prevented or treated. Hepatitis B is inflammation of the liver caused by the hepatitis B virus (HBV). HBV can spread from a mother to her baby during delivery. You will be checked for HBV as early as possible in the first trimester of each pregnancy. You need the test even if you received the hepatitis B vaccine or were tested before. You may need to have an HBV infection treated before you give birth.
Urine tests may also be done to check for sugar and protein. These can be signs of gestational diabetes or preeclampsia. Urine tests may also be done to check for signs of infection.
A fetal ultrasound shows pictures of your baby inside your uterus. The pictures are used to check your baby's development, movement, and position.
Genetic disorder screening tests may be offered to you. These tests check your baby's risk for genetic disorders such as Down syndrome. A screening test includes a blood test and ultrasound.

Follow up with your doctor or obstetrician as directed:

Go to all prenatal visits. Write down your questions so you remember to ask them during your visits.
