pls helppls help no judgment

so me and my bf had unprotected sex a lot. we were on vacation and forgot condoms and the resort had none so we just acted stupid. anyways, we did it the day my period ended- the day before my predicted ovulation days.(i attached a ss of the dates and highlighted in purple the days we had sex) he never came in me but i’m just wondering should i take a plan b? i took one a few months ago and i hate taking them bc they mess up your hormones but obviously i’m gonna take one if it’s necessary, my bf said he’ll buy me one but i’m not sure whether to take it or not. is it worth the risk..? pls lmk no judgment pls!!
