On October 6th I was drunk at a party and ended up having sex. We used a condom but we were so drunk and we didn't really know what was happening so just to be safe I just took "Next Choice" the next day October 7th. After taking the pill a week later I had brown discharge for a day and ended up bleeding for two days then after that I didn't get my period for the month of October. It's November 19th today and I still haven't gotten my period,I have an irregular period but I usually get it in the middle of the month or the last week of the month,it's almost two months since my last period,am I pregnant? We used a condom and I took the pill just to make sure. PLEASE HELP ME.
