hi people, i'm on birth control pills, at least i was and i had unprotected sex. my story: i took my first pill (i started to be on birth control) 4 weeks ago, almost a month. first three weeks (21 days) i took the pills regularly then, when i started my 4th week pack of pills in the first day i forgot to take it. i was scared to take it again next to that and i didn't took it the entire 4th week (7 days of not taking them). i literally was on birth control for 3 weeks and then completely stopped. after a few days of missed period i got an unusual light and unusual short lasting period (no more than 3 days). what scares me is not my unusual period but the fact that i had unprotected sex in my 7th day of not taking the pill and my partener finished inside me (he thought that i'm still on birth control pills). now i really would like to know what are the chances of getting pregnant? does the 3 weeks pack of taking birth control pills help me to avoid the unplanned pregnancy? the sooner i'm going to get an answer the better it is going to be...
