hello, I just want to ask if there is a possibility for me to get pregnant if we had intercourse a week before my period but I'm using a morning pill after our first intercourse and until now I'm still taking the pill. I'm expecting to have a period Nov.8 but we had intercourse Nov. 2, Why is it I don't have my period since it's been a week that I expect i have my period. I still continue using the pill every night.
