I am about half way through the first pack of birth control pills, i had sex with no condom and he isn't sure if he came should i take plan b in case?

Yes: There is a possibility that you could get pregnant halfway through the first pack of bcp with no condom use. If you dont want to be pregnant, then you should consider plan B asap. In these times, it is not a good idea to have sex without a condom, unless you and your partner are in a committed relationship and have both been adequately tested for stds.

Uncertain: It depends on which type of oral contraceptive you are using. Your pharmacist can help you to find out when yours began providing effective coverage against pregnancy. Base on this info - you can determine whether on not an emergency contraceptive is indicated.
