13 Weeks Pregnant
When you are 13 weeks pregnant, you may start to "look pregnant" -- you may have a "bump." During week 13 of your pregnancy, your baby's fingernails should appear and several organs (such as the lungs and stomach) should develop into their final functioning form. In the thirteenth week of your pregnancy, you may still feel tired or have some abdominal pain as your body adjusts to the pregnancy. At 13 weeks pregnant, it's important that you continue to get the essential vitamins and minerals your baby needs.
You are 13 weeks pregnant -- this is the last week of your first trimester! The first trimester ends when the fetus is about 12 weeks old, which is about 14 weeks from the first day of your last menstrual period.
During week 13 of pregnancy, you may find yourself starting to actually look pregnant -- you may have a "bump." Also, your morning sickness and moodiness may finally be getting better.
Your baby is now 2.6 to 3.1 inches long, crown to rump, and weighs in at 0.5 to 0.7 ounces.
