HELP, plan b?!

So i’m dumb, i’m sooo dumb! Me and my bf had sex earlier in the day where he finished; later on we were in the mood again and we were fucking but he never finished, cause he usually will tell me to get off him so he can jerk off. anyways, we stopped because we had to eat dinner wnd when we came back downstairs he told me “it felt like something came out but i didn’t finish” and i was like, “hm..” there’s usually precum on his tip when i give him hand jobs or if he’s turned on but he says he never feels it but he said for this it felt like soemtjing came out. i asked if it could’ve even been pee??? he said no, he honestly doesn’t know: it’s dumb, we should’ve been using protection, but my period is only 2 days away. he wants me to take the pill but im not sure if i need it??? what do u think? and i know, once again, im dumb for not using protection but i honestly don’t know if i should take the pill or just wing it
