I forgot to take 1 of my birth control pills and had unprotected was can i get pregnant?

Double up : If you forget to take one birth control pilll you simply double up the next day. This does decrease the effectiveness of the pill but not by much.

Depends. : If you take a combined pill with both an estrogen and progestin then the pack will still be effective. However, if you take a progestin only contraceptive pill then you are at risk of pregnancy.
