Pregnancy symptoms during week 4

No symptoms?

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.

Tender, swollen breasts

Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.

Fatigue

For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.

Nausea or vomiting

Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.

Make a prenatal appointment

If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.
