I think it’s probably unlikely for the 13th but you’re definitely in with a chance for the 10th! You can get pregnant when only trying once in the ovulation window
@Laura when did you get your positive? Congrats!
I got my bfp at 7dpo and thank you
I think so! I've been trying to work this out myself. I think ovulation occurs within 24 - 36 hours of your first positive OPK, and 8 - 20 hours of your peak. It's kind of hard to pinpoint... but as you had sex the day of peak I think you should be covered. The next time was probably too late as it would be after ovulation
