Did I ovulate on the 8th or the 9th?

Brittany

So I got my positive opk on the 8th around 7pm. I'm wondering if we don't normally ovulate until 12-36 hours after a positive why does glow mark it as the night I got the positive opk? I also never got my ovary twinges that I normally feel with ovulation and this has been my only positive this month. Really hoping this is the month...I'm super tired of baby dancing so much lol. Hubby is really trying hard which takes some of the pressure off me, but lordy lordy!
