Havent been on birthcontrol for a week, yesterday i started & doubled up & today too. last night i had unprotected sex, should i worry? what do i do?

Plan B: If you have been off the bc pills for a week and doubled up the last two days, you are not protected from pregnancy during this cycle. Important to use Plan B or emergency contraception within 120 hrs (5 days) of intercourse. Emergency contraception is available as an over the counter medication at a pharmacy. Contact your doc or family planning clinic if you have any additional questions.

Not to scold, but...: Don't do that! don't skip pills (any prescriptions) and if you do, don't double up. Don't have unprotected sex (unless you know your partner has no disease) even if you are on the pill carefully. - so, depending on your ovulation date, you could conceive, depending on the guy, you could catch an std. Worry won't help. See a dr., have tests, take better care of yourself - you're valuable!
