Your First Trimester of Pregnancy

You miss your period during the first trimester of pregnancy and discover that you are now pregnant. Your breasts become tender and are slightly bigger.

Frequent urination during the first month of pregnancy is an early pregnancy symptom.

One of the first signs of pregnancy is fatigue, often times extreme, but headaches and mood swings are also common. Your emotions might seem out of whack. If you feel like crying for no reason, it's ok. Go ahead and cry. Your partner will understand as long as he knows he's not responsible. More on your body and your baby below:

First Month of Pregnancy

Your baby is about the size of a dime during this first month of pregnancy. He has eyes, a mouth and a head and his legs and arms are growing. His heart has begun to beat and his lungs have begun to form. He is about half an inch long at the end of this month of pregnancy.

Second Month of Pregnancy

All of your baby's organs are present now. He is about an inch long and weighs approximately an ounce.

Nausea associated with pregnancy usually begins this month of your pregnancy. Some women experience very little morning sickness while others have it all day for most of their pregnancy. You may experience facial break outs because of the change in hormones needed to sustain your pregnancy. You should have your first prenatal visit this month. It is important to begin taking prenatal vitamins as soon as you discover early pregnancy symptoms and confirm it. Folic acid and calcium are important for your growing baby and help to prevent birth defects.

Third Month of Pregnancy

You will be able to hear your baby's heartbeat through a stethoscope this month. Your baby has fingers, toes and soft nails. By the end of this month of pregnancy, he is four inches long and weighs a little over an ounce.
