i feel like an idiot having to ask this because i know i screwed myself over by not just wrapping it.

i had sex with my boyfriend tonight on a whim with no protection, and i figured i would just take a plan b in the morning. my boyfriend did not ejaculate but i am fully aware that precum poses a risk of fertility.

however! i just checked my chart (should have done that before!!!!) and i am right smack dab on my fertile window. upon further research i find out plan b is not actually effective when ovulating!

so, what do i do? should i take a plan b anyways just in case the ovulation prediction is off? what are the odds of conception from precum alone (if it was even produced)? i know it varies and conception can tend to just be purely consequential so this probably isn’t something someone can answer. but is there anything else i can do to prevent pregnancy in this situation? i have definitely learned my lesson - thank you guys in advance
