Is this normal?

So I’m almost done with my placebo pills on my birth control and I still haven’t gotten my period but this happens all the time but it just seems later than usual. Not to mention I’m a bit on edge because I had unprotected sex on Wednesday and he pulled out and I took plan b on Friday which I understand can make my period come late or early it it’s the first time I’ve taken plan b.

I know this post is a bit all over the place but answer the poll about periods normally being late on placebo pill week but if you have anything to say about this period specifically with the plan b please comment
