This week highlights

It's a date!

Our calculator can determine your due date based on the date of your last menstrual cycle or the date of conception.

The embryonic stage begins

Thus it's rather a shock when you first encounter Nick D'Aloisio striding into London's Bar Boulud restaurant, firmly shaking hands and proceeding to outline his entrepreneurial vision. To imagine him in person, picture a Silicon Valley CEO blessed with an easy manner and 97th percentile media skills. Picture a guy who can confidently expound (while maintaining steady eye contact) on topics ranging from Noam Chomsky's theories to the science of neural networks to the immigrant mind-set to the Buddhist concept of jnana. And now picture this fellow trapped inside the gangly body of a British teen who might easily be mistaken for a member of the pop boy band One Direction-clad in a hipster T-shirt beneath a fitted blazer, hair swooping over his forehead, taking bites of a cheeseburger between bold pronouncements.

Today, the Financial Times reveals the fake gross domestic product data routinely released from many northern Chinese regions. There, solid alternative evidence suggests the authorities have “smoothed” the economic growth figures. They artificially boosted growth figures between 2012 and 2016, masking a real downturn, and last year covered up a genuine recovery.
发展最迅速的初创公司往往具有全球化的视野。未来一年,美国总统特朗普已经实施的移民限制,以及英国作为退欧的一部分而在考虑的限制措施,可能会对企业招聘形成障碍。

Indeed. That's an understated benefit of Philly tanking so hard in recent years: they are so bad it disincentives other clubs from tanking because they'll struggle to be as bad as the Sixers. The Mavericks are in the mix, at least.

Jobs will take a medical leave of absence until the end of June because his health problems are "more complex" than he had thought, shocking investors and sending the company's shares down as much as 10 percent on January 14, 2009.

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.
