Yes, it's true, you may be at risk for pregnancy if you had condomless sex after missing some birth control pills. Your exact risk depends on a few things, like which week of your pill pack that you missed your pills. For example, missing two pills at the very beginning of a new pill pack puts you at high risk for pregnancy. Missing two pills in the last week (where the pills don’t have hormones, they are just reminder pills) does not increase your risk for pregnancy. Depending on what week you were in when you missed your pills, you may need to use a back-up method of birth control (such as condoms) for 7 days until your pills are effective against pregnancy again. There is a very handy chart that you can check to see how to restart your pills and whether you need a back-up birth control for the next week. If you had sex within the last 5 days, you can come in to get emergency contraception (the morning after pill). Please come in as soon as possible so we can help you get this medicine. If you are not able to come to the clinic, one kind of emergency contraception (Plan B) is available without a prescription at most pharmacies.
