plan b help

i had the medication abortion 1/8/22 and haven’t had a period since i stopped bleeding.

but last night me and my bf were having sex w a condom and he pulled out halfway through finishing but we seen that it was broken

so we wanna take a plan b but i read it’s less effective if you’re bigger.

so should i take 2? i’ve taken plan b before but i was 40 lbs less
