Regardless of whether or not you think Snapchat is worth the $3 billion Facebook offered it, one thing is clear: There's an appetite out there for so-called ephemeral networks, where content literally vanishes seconds after being received. And, contrary to popular perception, this isn't just about sexting and X-rated selfies (though it definitely is about that, too). As content on the major networks becomes more corporate and commoditized, Snapchat and services like it restore some of the fun and spontaneity to social media. Just like a real-life interaction -- where ideas flow freely and you generally don't worry about everything being recorded for posterity and broadcast to the world -- SnapChat and networks like it offer a channel for genuine, unfiltered exchange. And the kids really like it. While Facebook's own CFO officially acknowledged last month that teen use of his network is declining, the number of teens on SnapChat -- at least anecdotally -- is exploding.

Some hits have gone so far over the top they should be winded, yet instead keep on puffing gusts of hot air, including “Downton Abbey,” “Scandal” and “Revenge.” A new addition on ABC, “How to Get Away With Murder” was a fun substitute, a lurid nighttime soap opera about lawbreaking defense lawyers — “Law & Disorder.”

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.
