So I'm on my 3rd day of the sugar pills on birth control and I have only had protected sex with my boyfriend twice. Like we have only done the dead twice in our entire relationship of like 2 years. I recently got on Birthcontrol, but I have made him wear a condom and we don't go long enough for him to ejaculate. I still haven't gotten my period. is it because I did something wrong? Or is something off? I am an athlete who used to get it every 3 months (when i was not on birthcontrol) so now I dont know what exactly my cycle is suppose to be. Can someone please answer my question. thank you.
