Pregnancy Home > 7 Weeks Pregnant

When you are 7 weeks pregnant, your baby is a little bigger than the top of a pencil eraser and weighs less than an aspirin tablet. During the seventh week of pregnancy, you may experience symptoms such as constipation, excess saliva, and morning sickness. At 7 weeks pregnant, you will develop a mucus plug, which forms in the opening of the cervical canal and seals off the uterus for protection.

7 Weeks Pregnant: An Introduction

When you are 7 weeks pregnant, you are in your second month of pregnancy. Your baby is now about 0.2 to 0.52 inches long, or about the size of a marble. He or she weighs about 0.03 ounces.
During this time, you should be aware of the risks the animals in your home may present to your baby, which is growing rapidly during this stage of your pregnancy.
