hi im 20 and have been with my boyfriend 4 years. ive been on jasmine elle the whole time. i started my 7 day break and got my period id had unprotected sex a day before i was to start taking the pill i took one pill but went out drinking and had been sick i didnt go back on my pill because id lost it! 4weeks and 2 days later i still dont have my period. i was just wondering if its possible that coming of the pill the way i did has made my period take longer to arrive?
