help!

i had a plan b the day before ovulation. we didn’t have unprotected sex until i think four days after that. (we also had sex before the plan b) i haven’t taken plan b too often so i’m not fully educated! i’m 23 i know i should read up on it more but can someone tell me if i’m somewhat safe?

my period is due in two days and i have SEVERE acne which is rare. is that from the hormones of the pill?

edit: i took the plan b directly after intercourse that was the day before ovulation. we didn’t take a plan b the days before and only took one. i don’t want to take birth control because we’re just putting a pause on ttc due to the pandemic. we were actively trying before this :)
