So me and my boyfriend had sex last night and he was wearing a condom but it broke. He came inside me and we were both freaking out so we went straight to the store and bought a plan B pill. I took the pill approximately 20 minutes after it happened. I'm on birth control too but 2 weeks ago, I was late taking 2 pills. The next three days of my pack, I was on time taking them. The next week I started my period. So I just got off of my period when this happened. Should I worry??
