<s>[INST] Hi. Me and my girlfriend had unprotected sex 1 am, but due to anxiety (mine) i didn t release any sperm at all. I made her take nordette this 6 am, then later at 6 pm. Sex happened two days later after her fertile days, and She said she had a regular menstrual cyle for the past two months, when would we suspect the bleeding? [/INST] Hi, your girl friend had regular periods, in last 2 months, and after unprotected sex she had nordette, so she must have period, with in a week of the pills.                           Any how why do you play with the natural process,you can have other physical measures. With this she will have total reshedule of the periods. So take care of the both. Thank you. </s>
