Pregnancy Signs & Symptoms, Week by Week Pregnancy Guide

At your 10th week of your pregnancy you are in the final stage of the first trimester. First trimester includes first 12 weeks of the pregnancy. At this stage you may wonder what your baby looks like.

Now you will start seeing some alterations. This period is the official start of the fetal development in 10 weeks pregnant. In this period the tissues and organs in the baby’s body will hastily develop and mature.

During this stage, it is very important for the pregnant women to take care of themselves to have a healthy baby.

Here is the fetal development in the 10th week.

Size

Now your embryo is known as fetus. Your baby is about 0.9 to 1.2 inches long when measured from crown to rump, and weighs about 0.07 ounce.

Movements

Though your fetus is moving constantly inside your womb, you actually will not be able to feel the fetal movements for some more weeks.

Feet and hands

As the feet and hands develop toes and fingers, they lost the paddle like look. The touch pads form on the fingers and already they have fingerprints.

Until 9 weeks, the reproductive apparatus of the fetus is similar for both the sexes. During 10th week, if it is baby boy he is forming his testicles. And around this week, the testes begin generating the testosterone hormone. If it is a girl baby she is forming ovaries.
