Hi sorry if this is tmi I'm 8 weeks pregnant, partner and I had sex this evening and after when I went to bathroom and wiped there was a very light pink twinge to the stuff on the toilet paper. There was nothing after just this once. This is my 3rd pregnancy in the space of a year the other two ending in MC and this has terrified me. Is it anything to worry about or could it simply be because we've had sex I have no pain or cramping just excessive worry
