What is normal and what is not? Advice from a leading maternal-fetal medicine physician.

warning signs pregnancy: pregnant woman talking to doctor

Your body goes through many changes in pregnancy. It is difficult to know what is normal. Below we’ve listed the top warning signs during pregnancy and tips for knowing when to seek help. We’ve also included a list of normal changes that you don’t typically have to worry about.

Warning signs you should not ignore in pregnancy

1. Vaginal bleeding after 12 weeks gestation

Light spotting is normal before eight weeks as the embryo is implanting. Some spotting can also occur after sex or with a cervical infection. Bleeding with pelvic pain can mean an ectopic pregnancy. Bleeding after 12 weeks can also mean the cervix is shortening or dilating which can lead to preterm birth or miscarriage.

Call your doctor if:

You have bleeding after 12 weeks.

2. Contractions

Contractions are common in pregnancy and can occur from the second trimester until term. The Braxton Hicks contractions are normal and do not typically change the cervix or indicate labor. They are usually painless, feel like tightening or hardening of the uterus and occur irregularly.

Call your doctor if:

Your contractions are painful, regular or accompanied by any bleeding or spotting.

3. Decreased fetal movements

You should feel your baby’s movements by 18 weeks gestation. At first, the movements will feel like a fluttering but will get stronger as you get farther along. Fetal movements after 28 weeks are usually more regular and more common at night than during the day. Regular monitoring of fetal movements is a good idea for all pregnant women. Starting at 28 weeks gestation, count how long it takes to feel 10 movements. This should be done daily and in the evening (6-9 p.m.).

Call your doctor if:

You don’t feel 10 movements within two hours.

4. Leg swelling and pain

The changes of pregnancy place women at an increased risk for blood clots. Blood clots can be dangerous and require immediate treatment.

Call your doctor if:

You experience swelling and pain in one leg (calf). Find out if you have a deep vein thrombosis (DVT) or pulmonary embolism (PE).

5. Severe swelling, headache, blurred vision, high blood pressure

Swelling of the lower legs is common in pregnancy. However, swelling accompanied by a severe headache, blurred vision, spots in your eyes, or abdominal pain can be a sign of high blood pressure in pregnancy called preeclampsia. If you experience these symptoms, have your blood pressure checked.

Call your doctor if:

You have blood pressure of 140/90 or higher with these symptoms.

6. Pelvic pressure

As the baby grows, you will experience pelvic pressure and uterine stretching pains. You will also have a small amount of vaginal discharge during the pregnancy.

Call your doctor if:

The pressure turns into pain and the discharge becomes bloody or increased in amount. You should be evaluated for possible cervical dilation and preterm labor.

7. Pain with urinating or one-sided lower back (kidney) pain

Frequent urinating is common in pregnancy but you should not feel pain when urinating or feel back pain on one side. These could be signs of a bladder or kidney infection. Bacteria in the bladder or kidney can result in a serious blood infection and preterm labor.

Call your doctor if:

You have pain with urinating or one-sided lower back pain.

8. Headaches

Normal hormone changes in pregnancy cause the blood vessels to dilate. This can result in women experiencing headaches. A lack of sleep and discontinuing caffeine can also bring on more headaches. These common headaches of pregnancy should be relieved with Tylenol in most cases.

Call your doctor if:

You experience severe headaches, especially occurring in the front or back of your head. Severe headaches can be a sign of preeclampsia that may require additional testing or treatment.
