CM is confusing

Tea

I would think, I would be an expert in TTC by now, since my husband and I have been trying for almost 3y now, but I feel more clueless than ever. I have one question that I cannot find an answer to anywhere and I’m hoping some of you might help. So... a little back story. I’m trying to figure out my ovu based on CM tracking and doing ovulation tests. My husband has motility issues and I have irregular cycles (27-45days). My gynecologist suggested to try every 3rd day instead of every 2nd because of the motility issue. We mix it up. Anyways, yesterday would have been 2nd day, and according to Glow, my ovu day. I had a headache after work though and wasn’t in the mood at all, I also did the ovu test (using the one with lines, not digital) and it was negative, so we decided to try today. Stupid me, didn’t check CM. I just went to the toilet though, and saw egg white discharge on my panties. The question is: Is it too late to still try, after the discharge is already comming out? I’m super confused 🤔
