German Three:Mercedes-Benz begins to sag as new lower-priced Benz’s inevitably erode its once invincible “the best or nothing” status. At BMW, imminent arrival of a new 7-series cements its status as the preferred brand of Scarsdale, Shaker Heights, and Santa Monica. A new A3, starting at $30, 795, should nicely lift Audi’s sales beyond 2014’s 15% climb, and a new Q7 SUV should nicely lift profits.
《风骚律师》(Better Call Saul)，AMC，2月8日播出。这是文斯·吉里根(Vice Gilligan)与彼得·古尔德(Peter Gould)的《绝命毒师》的衍生剧，或许是今年冬天最受期待的新剧了。鲍勃·奥登科克(Bob Odenkirk)饰演狡猾的律师索尔·古德曼(Saul Goodman)，剧情设定在《绝命毒师》的故事发生之前，所以布莱恩·克莱斯顿(Bryan Cranston)或亚伦·保罗(Aaron Paul)至多只是客串出演而已。但观众们最喜欢的乔纳森·班克斯(Jonathan Banks)将在里面重现他在《绝命毒师》中的角色——冷静的行动执行者迈克·厄尔曼特劳特(Mike Ehrmantraut)。

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.
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.
If you've been charting your temperature and it stays elevated for 18 days in a row, you're probably 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.
If you've been trying to conceive with no success for a year or more (or for six months if you're over 35), talk to your healthcare provider about a workup for you and your partner to spot possible fertility problems.
