Thandibaby • I want to live forever
I was having a bath and washing "down there" suddenly I felt a bubblish membrane kind of sticking out a bit. I just took a look now in the mirror and it looks like something wants to come out. So devastated. No blood. Nothing. It seems to be going back up again while I lay down. I'm so scared. I think I'm having a miscarriage. I dunno what to do.
