Amniotic sac and yolk sac

BROADCHURCH (BBC America, March 4) David Tennant returns in the second season of this evocative British mystery, playing Detective Alec Hardy again (after a season as Detective Emmett Carver in the American remake, “Gracepoint”). With the British premiere scheduled for Monday, the producers have begun to talk a little about the show’s top-secret Season 2 story line, and fans may not like what they hear: Chris Chibnall, the creator and writer, told a British magazine, “It’s not another crime case.” Olivia Colman returns as Detective Ellie Miller, while Charlotte Rampling and Marianne Jean-Baptiste join the cast.

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.

Pregnancy checklist at 4 weeks pregnant

Take a pregnancy test

If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.

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.
