i am so confused about these thing

Hello everyone :-D , i am so confused if i might get pregnant or not , because i had sex alot of times with my new ex boy friend , but i took 6 tablets , it called as postinor( the morning after pill ) , its not allow to take over 4 tablets in a month , but i had no choice because we had sex alot in a month and we didnt wanna use condom , after the day he left me , i had period , but i am not sure that was it period or bleeding from what i took ( the morning after pill) o.O , i havent used the morning after pill for along time since i met that guy , thats why i thought that i wasnt serious when i took more than 2 tablets , and now i came back with my long term boy friend , we broke up once , but we just got back together , we just have had sex last nite , somehow , the condom broke down 8-| , evenknow that i have seen his sperms on my bed , so i thought that it wasnt too much sperm inside of mine , do you think that i might get pregnant with a small amount sperms ? but i am so confused what if i get pregnant , who gonna be daddy of my baby :$ ? because i have been told that sperm could stay alive inside of vagina from 3 days to 7 days , if the last period wasnt period , like i said it could be bleeding , i just wanna get some advises if i could get pregnant after 1 week period or bleeding?
Thanks alot :-D
