I am 27 weeks pregnant. I have been having a pain right at the top of my butt crack. Then i noticed blood in my underwear, so i freaked out. I realized my butt crack from the top of the anus to the small of my back is bright red and cracking. When i sit down, it feels like it s stretching. It s very uncomfortable. I just want to know what it s from and how to get rid of it. I shower daily, and have been using baby wipes after a bowel movement to keep it clean. I also put desitin on it, and it still hasn t gone away. Help me.
