厌倦了一成不变的生活?何不去探险,让身心重新焕发活力?毫无疑问,南极洲会是个好去处。亲眼目睹企鹅嬉戏,成群结队的海鸟飞过天空,要比观看电视纪录片更令人兴奋。想象一下,置身于雄伟冰山和原生态山脉构成的世界中,是多么刺激和美好的一件事啊!但要注意的是,南极洲地处极地,因此行前要做好充足准备。保暖靴、防寒外套、手套、羊毛袜和帽子一样都不能少。

SETTING: Stonington is on Little Narragansett Bay in southeastern Connecticut, about an hour by car from Hartford and Providence, R.I., and three hours from New York City. Once a busy harbor with a long maritime history, the town remains home to a commercial fishing fleet, several historic districts of Colonial and Federal houses and a healthy sailing community. There’s a small public beach at the tip of town and another, much larger one in Watch Hill, R.I., about a 20-minute drive away. This Greek Revival house, with the requisite Ionic columns and a fan window in its pediment, is in the center of town.

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.
