Hi, me and my partner made out on 12th aug, we used condoms and even didn't have intercourse. We were just nakedly rubbing each other's part. After 10 minutes she had her periods, till that we thought we are safe. I ejaculated inside condom and at that moment the condom got removed and I controlled myself to step out from her and let the sperm came out after. And I was not sure about if any siemens had gone into her or not though we didn't have intercourse, to be in the safe side I decided to give her i-pill within 24 hours and she did so. Now it's september 15th, she hadn't have her periods yet, is it because of i-pill, is there anything to be worried about? Should I wait more.
