TMI when did i ovulate? OPK and CM pics

So I’ll post a few pictures. This is all that is logged in so it may not be accurate. It’s supposed to be my fertile week. I didn’t have opk for before expected fertile week. So the top test was done 3 days (10/22)ago at 950 am the middle was done 650 am yesterday (10/23)and the bottom done today at 5pm(10/24).What day do you think I ovulated. I BD on Sunday morning. I had two days of clear stretchy CM then one day of kind of just creamy then yesterday was clear stretchy again and then I had this CM just now 930 pm. Is this fertile or just regular discharge? I know that you’re supposed to check twice a day but this is my first month off the pill and as you can see I haven’t had a period for awhile now and didn’t know when to start opk. Could I still BD tomorrow or am I too late ?
