Your little embryo

It was an incredible achievement for SpaceX. The first stage rocket of one of its Falcon 9 launchers, having successfully lofted cargo to the International Space Station, managed to turn itself around, bleed off the enormous kinetic energy it had acquired while its main engines were burning, fly back down to Earth and land vertically - with balletic precision - on a rather tiny looking robotic barge floating somewhere in the Atlantic.

The mega-retailer didn't have a whole lot to complain about in fiscal 2010. Profits were up and, thanks to its sales, the company once again climbed to the top of the Fortune 500. Same-store sales were about flat for the year, but compared with Target's 2.5% decline, flat is good. Most remarkable was Wal-Mart's image overhaul. It helped that former CEO Lee Scott beefed up health care coverage for employees, thought more about the environment and became a public presence. Certain critics will never be placated and fiscal first-quarter results weren't the greatest. But there's no denying Scott left new CEO Mike Duke a company in fighting form.

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.

调控精准发力推动经济稳中有进

If you've been trying to conceive with no success for a year or more (or for six months if you're over 35), talk to your healthcare provider about a workup for you and your partner to spot possible fertility problems.
