I had my period on the 20th and it ended on the 25th, that day I had unprotected sex. However, even though he didn't cum inside, I still took the pill as an extra precaution to be sure. I took it 2 days later, on the 27th within 72 hours like recommended. It's now exactly 7 days after I took the pill, July 3rd. I now have what seems like my period. Moderate bleeding, cramps, back pain, nausea, moods swings. You know, the usual icky symptoms when you have your period. But I just had my period 10 days ago, and had sex the same day it ended. Have any other girls experienced the same, is this a normal side effect?
