Early ovulation? Is it possible...

Glow says my O day was the 8th (my periods have been a little funny the last few months).. we BD on the 31st, 1st and 2nd I just felt very in the mood. On the 3rd I had A LOT of EWCM (tmi I know it was ewcm and not sperm)

Is it possible to have ovulated early or am I out this month? We didn’t get to try throughout the week due to him being out of town.
