Please help!

So I don't know if I'm being paranoid or if it's normal but two weeks agai my boyfriend and I have sex unprotected and he came in my. In result we took the plan B after pill. But the following week it happened again( I know I was pissed, I ripped him a new one.) So again I took the pill. Now I was suppose to start this week and still haven't but I know on side effects it says that I may start my period up to a week late. The only other problem is that I am suppose to start my blue pills yesterday for the pill. I'm confused and don't know if I should continue using my pill? Or if I won't start because my pill?
