precum

?

so, i had unprotected sex two days ago. he didn't cum, im in my less fertile week (according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> which i know isn't 100% reliable, I had a 3% chance of pregnancy) and my period is due in 3 days. everyone freaks out about unprotected sex, i know, and please don't give out to me for not using BC but what are my chances of getting pregnant on precum with a, roughly, 3% chance of pregnancy? im not in a place where i can just take a rest or order the morning after pill because i live an hour away from the nearest pharmacy and next day delivery takes 3/4 days to get here
