25 Weeks Pregnant: Your Baby’s Development

All filled in. Your baby's skin is still thin, wrinkled, and pale, but she gets a bit plumper every day, thanks to the fat and muscle she's continually adding. Right now tiny blood vessels called capillaries are starting to develop below your little one's skin, and these will give it a pink hue.

Brain gain. The brain's cortex is developing into elaborate layers. Most of the action is still controlled by other brain areas that developed much earlier.

25 Weeks Pregnant: Your Symptoms

Having a ball. Your uterus is now about the size of a soccer ball, so it's natural that your organs are feeling squished. Measuring from your pubic bone up to halfway between your belly button and your sternum, your uterus is about 25 centimeters in diameter.

Diabetes check. Performed between 24 and 28 weeks, a glucose screening test looks for signs of gestational diabetes, a high blood sugar condition that affects 2 to 5 percent of pregnant women and usually goes away after birth. The test itself is simple: A few minutes after drinking a sugary solution, your blood is drawn and your sugar levels are tested. If your blood sugar is high, another blood glucose test is performed to determine if you have gestational diabetes. Treatment involves a special diet and, in a few cases, medication.

Telling symptoms. Urinary tract infections (UTIs) are very common during pregnancy, and they may be caused or aggravated by not urinating promptly or completely. One sign of a UTI is a need to urinate frequently. Another is a feeling of urgency — like you really need to go — but nothing happens. You may feel burning or pain when you urinate, or your urine may have an unpleasant odor. If you have these symptoms, call your doctor right away. UTIs are easily cured but can cause very serious complications if left untreated during pregnancy.
