What do i do if i missed a birth control pill and the next day pills are brown?

Placebo: If the brown pills are your placebo iron pills at the end of the pack, then you should be ok. It is always safe to add condoms, when you are not sure if you are right on your bcps.

Take right away: It looks like you're a male asking about birth control pills, so i'm assuming you're asking for your girlfriend or wife. If a woman missed a pill, she should take the pill as soon as she realizes it the next day. If she misses 2 pills she should use a back up method for the rest of the month. If by brown pills you mean placebo week, then you should be okay, just take 2 pills to catch up.
