I've been on birth control for about 3 or 4 months now, my boyfriend & I have used a condom ever since I started but just had unprotected sex last night because the condom broke & again tonight. He pulled out both times. I didn't start my birth control on the Sunday of my period & am now worried it may not be working because I started it the Sunday after my period. My periods are light, barely any cramps, but my last one was very light. Thank you!!!
