Your baby is about the size of a poppy seed

Primitive placenta

I mean, is it worth to be a No. 8 seed with Serge Ibaka and Jeff Green leading the way? Maybe it is. This all just seems awfully backwards.
It even featured in the March 19, 1870, issue of Scientific American magazine. Made by Thomas Luders from Olney, Illinois, and called a "pedespeed," the wheels then were much smaller, measuring around 36 centimeters (15 in) in diameter. Luders also said the skates could be used by anybody, irrespective of their physique. He himself was a large, heavy man, and he claimed he could use them for two straight hours without getting tired. Another version of wheel skates, appearing in 1923, had its tires on the inside of the foot rather than outside. (Other than the size of the wheels, the main improvement made by Chariot Skates is the small tire at the back of the bigger tire for increased stability.)

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.
