What will happen if I took my first birth control pill before my period came on... Did I just mess up my cycle... Or will it come on when I get to the end of the pack???
Is this the first time you have taken the pill recently? You will just need to make sure you use other contraception alongside it for 7 days (condoms or another barrier method), as the levels of hormones will need to build up to protect you from pregnancy. If you mean you started you next pack straight after another, before your period arrives, you will just miss your period this time, but still be protected. In either case, your period will arrive once you have taken every pill in this current pack.
ok. . I took my birth control pill before my period. will anything happen?
