I took plan b may 2nd, got a period 1 week later, had unprotected sex may 31st but he did not ejaculate inside of me, but did so near my vagina. I have taken 3 pregnancy tests, all negative, most recent neg test was June 14, to double check to see if I was having breast pain and nipple tenderness due to plan b being ineffective as I found out after taking the pill I am over the weight limit for it to be effective. I also have pcos. Is my breast pain causes by plan b even after all of these times? Or is it a pregnancy symptom?
