A condom broke after missing pills of birth control that i took late and this is the week if my cycle i get my period but it is brown what do i do?

Preg test: Missing one pill does not usually matter. Take a pregnancy test 10-14 days after sex or if you miss your next period.

Brown menses: Your cycle maybe a little slow in beginning. If you don't have a normal flow in several days i suggest that you go to your md and have a blood pregnancy test. If you don't want to be pregnant it will be early enough to have a safe termination.
