High chances? I’m worried

Hi ladies.

I have taken plan b second week of January and in the past my period would always be on the same time maybe a day before (I have taken plan b many times in past) so fast forward me and my BF had unprotected sex a day after I “ovulate” and the second time this month was yesterday which 3-4 days before my “expected” period. He pulled out both Times.

I know plan b may mess up the cycle but in the past it would be fine for me...

I rested days ago before the second sex encounter and it said negative. Should I be worried?

Thank you
