I have been taking birth control for almost four months now. My period has been a little irregular. Since I am just starting birth control, the second month, my period came a week earlier and was more spotty. This month was my third month and my period came a week early again, but there was also spotting before starting my period. Me and my boyfriend recently had sex while I was on my period and we didn't realize the condom broke inside of me. Do I have a risk at getting pregnant or should I be alright?
