Did ovulation likely happen or should I expect it soon?

So I've never caught my surge doing this before but I don't normally keep testing every couple of hours like I am this cycle. My LH started to surge with my ratio on Premom going to 0.88 (11:33am), then it dipped to 0.59 (5:52pm) even though my urine was extremely concentrated and darker than the previous test, then I was hydrated better and it rose to about 1.00 (9:36pm). I had some cramping this morning and throughout the afternoon until around 9pm. Should I assume I already ovulated or do you think I'm ovulating soon? Does anyone else here experience this weird roller coaster pattern during your LH surge? I'm wondering if we missed the window or not and previously I never caught my LH going up then down and back up again. Thank you in advance for any shared experiences and information!
