Hi me and my boyfriend had sex on the 23rd of November it was on a Wednesday and he came into me, l took the morning after pill on Friday the 25th of November and the next day l began to ovulate. My period was supposed to come on the 16th of December but it did not come, so l just thought maybe its the pill which is delaying the period, but l got tired of waiting for my period so l took a pregnancy test and it came out to be positive. My question is how did l get pregnant when l took the morning after pill?
