Some 18.1 million people, for example, want a good full-time job but can't find one, an unusually high number 5 1/2 years into a recovery. And despite a sharp decline in the number of people out of work six months or longer, that figure is still higher than at any time before the 2007-09 recession.
With another Fast & Furious movie slated to hit theaters next summer, Johnson should have another banner year in 2014. He could do even better thanks to Hercules. The film, about the mythological hero’s life after he completes his famous 12 labors, has franchise potential written all over it. If it’s also a big hit, Johnson’s 2014 box office grosses should be huge.

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.
