Hello, and I hope I can help you today.
There are two main possibilities of what you may be noticing on your
perineum, both of which are common during
pregnancy.
The first possibility is that the extra skin is actually a skin tag, which is a bump that grows from a combination of the hormones of pregnancy and the skin in the area rubbing against itself or your underwear. The following is a link for some images for vulvar skin tags: http://s3.yyyyyyyy.com/f01.juyyyyyyy.com/JACUSTOMERn0orgmgx/2014-03-01_201304_20140301_134800.jpg
The second, and more likely diagnosis, is an external
hemorrhoid. Hemorrhoids are bulging veins near the anus that cause the skin overlying them to grow more- causing the appearance of extra skin. Here is a link to a picture of a typical external hemorrhoid: https://www.ay.com/mya/gallery/photo/cyyyy/1/image/640x480/9df78eayyyyyyyyyyyyyyyyyyyy/8/5/85.jpg Hemorrhoids can sometimes itch or bleed if they get larger; if you experience these symptoms you should contact your
prenatal care provider.
The good news is that both of these conditions usually resolve after the baby is born and require no treatment. You may find that other
moles on your skin may get larger during pregnancy as well, and they typically decrease in size after the birth.
So I hope I was able to answer your question and that these images help clarify your condition.
Best wishes for the rest of the pregnancy,
Dr. Brown
