I think I had a blood blister on my vagina. At least that's what I thought it was. I have never had a blood blister but looking at other pictures that is what it looks like. But to be fair I can only see it if I take a pic because of my big belly. Anyway I popped it so days ago because it really hurt and ever since its been leaving spots of blood in my undies. Is this normal for a blood blister. I had to pop it some more yesterday and more blood came out. There is only blood no other liquid like pus or anything.
