So I need you guys help on this. I was supposed to have my period last week Saturday but it never came on didn’t know until Wednesday. So Saturday I had sex with my lovely boyfriend and ofc I was fine. So Tuesday came I noticed my period was coming on, like a light pink  reddish color(so I said ok my period came on) then that same night in the middle of the night I used the bathroom noticed  it was darker but with tissue lining (I said ok boom we working with something, keep in mind nothing was heavy at this point) then I woke up the next morning and I have no period. I’m like what’s going on. So what does this mean. Because this never happened to me after sex. It might come late but never one day and boom nothing. So need some answers guys? Can having rough sec do it? Or coming to hard? Like what are the possibilities?
