I recently started taking microgynon the contraceptive pill. 3 days into the course, during sex, I started bleeding like I was on my period. It stopped pretty much straight after though and haven't had any bleeding since. I have now been taking the tablets for about 2 weeks but am worried I will bleed again if I have sex. I'm not meant to be on my period for another 2 weeks or so. So ordinarily there shouldn't be a problem...
