On the 14th of November, I had unprotected sex. My partner did NOT ejaculate and he says that he is sure that no pre-ejaculation came out, but I realize that unprotected sex is unprotected sex and unfortunately anything is possible.
On the 16th of November, I got my period.
On the 17th of November (today), I took 1 out of 2 "Postinor-2" tablets (within 72 hours of the unprotected sex.) I did not have the second one as I could not find it.
My questions are: could I be pregnant? Would my period not have come on the 16th if I had been/was pregnant? The reason I am asking this question is because I know that there was basically only a 48 hour window between the sex and the period, so I'm not sure whether or not that would have stopped my menstrual cycle.
