HI well I have been sexually active for 3 months and within those three months I have had three yeast infections and I took four pregnancy test. My periods are irrigular and since my last period it seems end 18 days. It s usually every 32+ days I get my next period from my last one. Well last night I had sex with my bf and every time we do I let him cum inside me because I don t believe I can get pregnant last night after we had sex I d say about 10 minutes after or at least 5 minutes I had to go pee and wash up down there. Anyways when I went to go wipe after peeing there was light pink blood and a small sticky dark red blood clot. And after that i didn t bleed anymore plus it was the first time ever bleeding after having intercourse. I was wondering what tho could be I m scared and nervous please help.!!?
