I started taking the pill on April 27th, it is now May 10th, but my boyfriend ejaculated inside of me on May 8th, which was 11 days after starting the Pill. I know the directions say to wait 7 days, which a i did, I just have seen some people now saying a month. Just not sure if it would be a good idea to take plan B? or if I am probably fine? I have been taking the pill at the same time every night basically down to the exact minute. So am I fine? Or should I take the pill just in case? Only reason I'm really hesitant to take it is because I am not sure if I can do so while on the pill, and I don't want to mess up my period cycle. Thanks! :)
