Your little embryo

The world's first flying bicycle flew on November 9, 1961, when Derek Pigott of the University of Southampton flew in a bicycle with an airplane-like body. It was called the Southampton University Man Powered Aircraft (sumpac). Derek furiously pedaled the air-bike to get it off the ground. It then flew 1.8 meters (about 6 ft) above the ground over a distance of 64 meters (210 ft). While the flight was short and slow, it still does not change the fact that it was the first bicycle to fly and at the same time, the first human-powered flight.

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.
