Help-sorry for the long post

My boyfriend and I had sex a couple days before my period started. We were wearing a condom, he pulled out sat there and then came in the condom after that we stoped and went to bed — but any time he comes or is around cum he gets really nervous and wanted me to take a plan b which I wasn’t gonna spend $50 on that just Bc I knew there was no way I’d be pregnant. But now I’m 2 days about to be 3 days late but my last period I was 6 days late ?? Am I okay
