I need some input...

So my cycle usually lasts anywhere from 34-36, at the most. Well this month during my fertile window I had a pretty heavy amount of EWCM on the 12th so I made sure to BD just to be safe. I didn’t have any CM on my actual ovulation day or days before or after.

We didn’t get the opportunity to BD much during the fertile window cause my husband was home late, and just life.

My question is... what are the chances that I ovulated early, like around the 12th? And I don’t use opk to know for sure.
