This week highlights

It's a date!

Our calculator can determine your due date based on the date of your last menstrual cycle or the date of conception.

The embryonic stage begins

几年前,有人发明了一辆会飞的自行车,叫做"Paravelo"。称一辆自行车会飞,并不是开玩笑,而是这辆自行车真的会飞(车头有一个巨大的降落伞)。它在陆地和空中的时速分别为25千米(15英里)和40千米(25英里),可飞至1200米(4000英尺)高空。最棒的地方是什么呢?那就是你不需要有飞行驾照。Paravelo号称世界上第一辆会飞的自行车,但我们必须指出它并不是第一辆会飞的自行车。
Both the film and the television series are adapted from the Taiwan action role-playing game of the same name which was developed by Softstar Entertainment. The game is considered by many as simply one of the best Chinese RPG's ever created.

Consider carrier screening

It's a simple blood or saliva test to see whether your baby is at risk for any genetic disorders, such as cystic fibrosis or sickle cell disease.

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.

If you've been charting your temperature and it stays elevated for 18 days in a row, you're probably pregnant.

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.

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.
