The seventh month of pregnancy is the last month of the second trimester, and just as you've experienced for all of the months up to this point, your baby is growing and changing. As a result of this growth and change, you are feeling and looking different, too.

Size

The seventh is the time of most rapid growth for your baby. She is now about 15 inches long and 3 lbs. Your baby is adding fat under the skin at this point, and by the seventh month, about 3 percent of his body weight is fat, according to The Pregnancy & Babies Resource Center at The Hospital for Sick Children in Toronto.

Effects

Your baby's weight gain may make you feel heavy and even throw you off balance, so be aware of your posture, stand up straight and wear practical, low-heeled shoes. You may also feel pressure on your diaphragm, liver, stomach and intestines. You may even feel breathless sometimes because of the pressure on your lungs.

Features

Your baby is red and wrinkled during the seventh month of pregnancy. He can open and close his eyelids, and he's storing large amounts of calcium and iron, so it's important for you to continue taking prenatal vitamins if they've been prescribed by your health care professional. During the seventh month, your babies lungs are now capable of breathing air, and his nervous system is developed enough to regulate body temperature.

Recommendations

The Pregnancy & Babies Resource Center at The Hospital for Sick Children recommends that you keep track of your baby's kick counts. In the seventh month, your baby should be making at least 10 movements over a two-hour period. Or, you can track 30 minutes of kick counts. Your baby should be making at least three movements in a half-hour. If you notices any changes, contact your health care professional.

Warning

Some of the warning signs of premature labor are more than five contractions per hour, bright red vaginal blood, low and dull back pain, pain during urination and intense pelvic pressure. Contact your health care professional immediately. Your baby has a good chance of surviving if born during the seventh month.
