I'm just curious on when do you think I might ovulate

I'm on cycle day 21 with a almost stark white opk (testing morning and afternoon)

I've been testing since cycle day 10

With a clearblue digital till cycle day 19

Then with first response opk tests

My last cycle was 37 days so I'm asuming this cycle will be the same

I'm not stressed and the only things I've changed is I cut out sugers from my diet and no chocolate and stopped smoking ciggies 6 days ago

Anyone have an idea of what is going on

Is it possible I won't have a lh surge this month and not ovulate?

Anyone else have this issue??

Best of luck to everyone sending lots of baby dust ❤
