I took plan B about 30 minutes after the broken condom incident. I was suppose to get my period the day after the incident happened, but I took plan B and from what I've read it seems to be normal that it would delay my period. But it's been A week (7 days) sense I took it and still no spotting or bleeding. My breast have become tender, and I have had major cramps the past two days. I have been stressing and I'm well a wear that also delays my period, but I can't help it. Should I be worried? Or should I just relax?
