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.

Her childhood inspired her to focus on empowering women living below the poverty line through grassroots efforts. The Wonderbag, which was inspired by watching her grandmother cook with cushions, uses heat retention technology to cook food for 8-12 hours without the need for additional fuel. Collins witnessed the benefits African women received from using Wonderbags, reducing the amount of time they spent collecting firewood. For every bag sold, another is donated to a household in Africa, and in the past four years, the Wonderbags have found themselves in 600,000 African homes. Collins has launched the Wonderbag in the U.S. on Amazon, and hopes to sell the products via other retailers by 2014. [Accessed May 2019]
