Day 20 and haven’t ovulated

So I am 20 days into my cycle and according to the numerous opks I’ve taken, I have not yet ovulated. This is our first month TTC baby #2. The last four months my cycles have been perfectly 28 days but they have ranged from 28-37 days in the past. I have had EWCM since Saturday now so I am praying I get a positive ovulation test in the next day or two. Anyone else experience something similar to this? I don’t believe I have missed the surge as I have now been testing like 4 times a day!
