I haven't had sex in prolly over 4 or 5 months. I have already had sex b4 lots of time but I been goin through stuff n aint had the time. I had my period a lil over a week ago. Me and my new boyfriend had sex and I went to use the bathroom and I was bleeding really heavy. Is it because I aint had sex in 4 or 5 months?? Plz help. (Never been on birthcontrol)
