Please help

I’ve been having protected sex and on days me and my boyfriend would have unprotected sex I would take the plan B pill even though he pulls out just in case and my last period was between the 26th July - 1st August then I got period again between the 8th August - 12th August and I had unprotected sex on my last period but he pulled out and that time I didn’t take the plan B because he said I can’t get pregnant on my period and

should I be scared for pregnancy?? Or am I stressing for nothing and my period is coming?
