Hi. I had un protected sex the night of May 21st and took plan B one step the next afternoon. Then again the following Sunday night May 27th but used a condom because I was ovulating. Well, the condom broke. I called my local planned parenthood tues morning and she said I should be OK because of the plan b taken the week before and didn't see a benefit of me taking it again. Well starting yesterday I'm having sore nipples, cramps and period-like symptoms. Could this be because of the plan B messing with my cycle or is this symptoms of implantation? Freaking out!
