Here's a look into social media's crystal ball for 2014. Will Snapchat catch fire? Will those annoying Promoted Tweets keep invading your Twitter stream? Will your boss finally learn to tweet? These five trends are poised to shake up the industry and the way we use social media in 2014:
Behind the facade of many a New York City apartment building is the dissonant sound of residents complaining. The gripes that make their way to the inbox of my Ask Real Estate column offer a glimpse into how residents cope with the myriad irritations that come with living in cramped and costly homes. They include the co-op shareholder horrified by a neighbor’s rats’ nest; the parents whose building has barred them from using a stroller in the elevator; and the renter whose kitchen cabinets fell from the walls.
This habit can seriously hurt you in a work setting. If you’re one of those folks who believes that you do your best work at the last minute and put off projects or assignments until the day (or hour) before they’re due, you may not be aware of the impact your habit is having on your co-workers.If your last-minute rush requires others to work quickly, you will likely anger them, and you’ll be the first one blamed when a project fails or isn’t completed on time.

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.
