Last night when I went to L&D the girl who was checking me, made me bleed. She was going over what to do if thing started to happen. She said that I may bleed for 24 hours where she checked me. I also may loose mucus an it will be ....la la la. She then went over what to do if my water breaks an if I'm bleeding badly! So it's been 18 hours since I been there. I went to the restroom an there was lots of dark bloody mucus. Is it my mucus plug? Or is it from where she checked me?
