ladies I need some help please I just went to the restroom and when I wiped there was a little bit of blood on the toilet paper. I thought I was seeing things but when I wiped again it was still there. my husband and I had intercourse last night but I didn't have anything until just now. has this happened to anyone or should I call my midwife?
