I started birth control for the very first time on a Sunday start 3 days into my cycle. On Saturday (6 days after starting) my boyfriend and I had protected sex with a condom. However when he went to put the condom on it lightly touched the head and he realized it was the wrong way and flipped it. It didn't go fully on his penis. My worry is some precum got on whatever had touched it and i have the potential to be pregnant. Am I overreacting ??
