what do y’all think??

alright so i ended my period friday morning and had sex with my bf that night. the condom kept coming off so i took plan b just in case. the next night we had sex again and the codom broke he hadn’t ejaculated yet but we weren’t sure about precum so i looked it up and it said i would need to take another plan b and that it wouldn’t hurt me. i’m eight days away from my predicted ovulation btw. today i feel kindve faint/dizzy and super tired and i’ve had a headache. i think it must be from all the hormones. i’m supposed to start BC pills tmr morning from my gyno. should i take them or is this too much medication at once. i’m just stressing out and don’t want to be pregant or mess up my body.
