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

Every point we think we've reached where James cannot be better than he has been, he then blows past it like a poor center switched onto him. What will be discussed most is his all-encompassing skill, but this is also a testament to the work that James puts in. You can mock all those Instagram videos he puts up, but those are the real reason he's still able to do this; James has never cheated the game, not a day in his life, and the result is incomparable performance night in and night out.

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.
