I was on the sugar pills of my birth control when my boyfriend and i had sex. he came inside me and i never started my period afterwards. pregnant?

Maybe/not: If you have been on the pill for many months you are likely not pregnant. The pills generally work by preventing egg release so no egg= no pregnancy. The sugar pills are a spacer that allows your uterus to shed a normal menses. You are not especially vulnerable when you take them.Some women skip cycles occasionally. You can do a pregnancy test if you wish.
