I recently found out I'm pregnant. I'd like to figure out the exact day I conceived. The only two possible days would have been CD 9 and CD 19. My cycle is always either 31 or 32 days. 

 

Which day would have been more likely? Or is this not enough info to be able to tell?

Just based on the numbers you have given, I would say day 19 was probably more likely.

since it totally depends on when you ovulated, and you're not sure, it's hard to tell. with a 31/32 day cycle your ovulation day (and window) is probably closer to day 19 then day 9. most healthy luteal phases (phase from O day to AF) are at least 11 days, so you could ovulate as late as day 20, but i think it's more likely that you conceived on day 19.

 

i personally have 29/30 day cycles when i'm menstruating and I pretty much always ovulate on day 15.

Ah! I'm so confused now! I've had a couple friends tell me it was probably day 9, because if I ovulated on day 14 or 15, the sperm could still be hanging around. 

 

I guess it doesn't really matter. I'm not going to get too hung up on a due date anyway.

but ovulating on day 14 is assumed for a 28 day cycle, and rarely do women actually have 28 day cycles exactly with exactly day 14 ovulation. your cycle is about 4 days longer (32), so if you were going by the assumption that you ovulate halfway through your cycle, that would be around day 16 - which is closer to day 19.
