Please dont beat my ass

I have OCD and anxiety ok. To make it short I’ve been on birth control (yasmin 21 pills no placebos or sugar pills whatever) since April. Only missed taking it once and this was months ago anyways. This month for the past 2 weeks-ish I’ve been taking it as follows:

Nov 11: 8:31 pm

Nov 12: 8:20 pm

Nov 13: 9:49 pm

Nov 14: 9:06 pm

Nov 15: 10:00 pm

Nov 16: 8:19 pm

Nov 17: 3:45 pm

Nov 18: 8:51 pm

Nov 19: 9:33 pm

Nov 20: didnt take it until 2am next day (21 nov 2am) i think lol😓 i dont remember ugh

Nov 21: again took it at 4:51 pm

Nov 22 (today): 4:22 pm

I had unprotected sex today and he pulled out… but my anxiety is eating my head. Its 2AM and i cant get any plan b rn and dont want plan b to mess with my period (my period has always ALWAYS been consistent with birth control). Should i buy a plan b tomorrow morning or is it not worth it?
