can i get pregnant on this day of my cycle?

can i get pregnant at this point in my cycle?
i have pcos and suspected endo so things could be harder for me and i may be in luck as i have been a few times before!
but am i at risk for pregnancy with unprotected sex and accidental finishing inside of me without plan b on day 15 of my cycle?
my last cycle was 39 days
my cycle before that was 35 days
my cycle before that was 58 days
and then the other was 43 days
so not so irregular at the moment
so when do you think i should ovulate ?????
cos plan b won’t work if im ovulating will it?

Plan B and prevents ovulation and will do nothing if you’ve already ovulated. Ovulation typically occurs on day 14 in a 28-30 day cycle but it typically occurs later if the cycle is longer. Sperm can survive for up to 5 days and the egg for up to 2 days so theoretically you’re at risk of being pregnant if you ovulated between day 13 and day 20.

i haven’t had signs of ovulation yet. i have had severe cramps on saturday so could’ve been ready to ovulate then but other than that, ive had no discharge yet or anything like that or bloating yet.
so could be lucky but dont want to try plan b if it will mess up my hormones and not work anyway.
do you think i could be lucky and not be pregnant ???

It’s always more likely you won’t be pregnant than pregnant for a one off incident. A typically long and irregular cycle as well as no current signs means it’s most likely you haven’t ovulated this early in your cycle

thanks!! i hope not but i don’t normally get discharge during ovulation only white discharge sometimes. is white discharge a sign of ovulation?
