If I start the birthcontrol pills, how long do I have to wait b4 me and my bf have sexual intercourse without condom and without him busting inside me?

0 or 7 days. If starting the pack of pills on the first day of your menstrual period, they will work right away and you don't need additional protection. If starting the pack of pills on the first sunday or any other day of the week after the menstrual period starts, the use of a backup method of birth control (condom and spermicide) for seven days is indicated.
