I just started taking birth control, but I didn't time it right. I started taking it 1-2 weeks after my last period. After taking it for only 3 days, I had unprotected sex. They say to use back up contraception for 7 days after you begin taking them for the first time, so I took Plan B this morning just in case, but I didn't take today's birth control pill with it. Should I skip todays bc pill altogether? Take it this evening? or take it tomorrow with tomorrows pill? ... or what?

It's sort of an exceptional situation, I know after using Plan B while on birth control I need to use back up birth control for 7 days after.
