I unfortunately had unprotected sex with a friend of mine Saturday night and I've been almost period cramps times ten pain almost all day long since Sunday ??? I've had two kids and I was trying does baby #3 for along time til a few months ago when my kids dad and I broke up but I've never experienced this much cramping after sex and I completely forgot to log my period last this month but if it was same as last month I was ovulating 😫 I also am extremely wet and dischargey I just was trying to yell for my 8 year old and I felt like I pissed my self ???
