Ok girls I need some help I have never done anything like this but I'm worried but first my back store if you will ( I have pcos I was diagnosed at 17 the Dr told me it's so bad I could never have kids first time I had sex I got pregnant boy did I prove them wrong I have a three year old now) well I've been trying for almost 2 years for baby number 2 I've been on metformin Clomid I don't have a normal period at all I went over a year after my son was born with no period at all. But for pasted few months I've been having a period not the same days apart but still having one. I'm sorry if I'm confusing anyone told y'all I'm new at asking for help. But anyway my last period was the 2nd of this month I took Clomid 100mg on the fifth day had sex on and off from when the meds where gone. But here is my question we had sex this morning and when got done there was blood alot coming out of me it didn't look like period blood at all there was no pain at all. Do y'all no what it could be as of right now there is none and glow says my period is suposed to be the 29th of this month sorry for tmi but it scared me and I hope one of y'all can help me I'm 24 years old if that helps any thank you all that can help and God bless
