i was wondering the chances of me being pregnant are. so heres what happened, i started birth control pills nov. 16 and was only on it for about 2 weeks until i couldnt take the side effects any longer so i just quit. me and my bf had unprotected sex about 4 or 5 times after a week i was on the pills. 11 days after i started the pills my doctor gave me a different brand because i had a lot of spotting, i cant remember if i had sex with my bf for the 3 day day before i quit, but i just read you should wait a week before you have unprotected after starting new pills, is that right? i started the pills, nov. 16, the first day of my period and because of the spotting, and then after i got off the pills i bleed 3 days later for about 5 days. now im not sure when i should expect my period, if i count from the last day i bleed i should have had it today. how high are the chances i could be pregnant? and because of the birth control pills does it mess up the first period getting off them?
