Five months pregnant, the hospital B-ultrasound examination is a girl, but also a boy. What's going on here?

There will be some errors in B-ultrasound examination. Usually, the sex identification of pregnant women's fetus is B-ultrasound, but even the most experienced imaging experts need to identify the sex of the fetus in the third and a half months of pregnancy or longer, and the accuracy rate is not 100%.

In the second trimester, pregnant mommy should do breast care, dress appropriately and pay attention to the rules of work and rest. Exercise properly to enhance physical fitness. Pay attention to vaginal care and cleaning, and use drugs with caution.

You can do some breast massage once a day for 2-3 minutes each time, preferably before going to bed or after taking a bath. But be careful not to over-stimulate nipples, and don't do breast massage when you are tired or have abdominal pain.
