Little help with ovulation testing....

I have been doing ovulation tests for a about a week now and have watched it get darker as the days go by....last nights was still negative but slightly darker....almost positive (it was very nearly like the test line) but this mornings is a lot lighter? Did I peak in the middle of the night? I’m confused and a little worried 😟

Just to add....I’ve been temping to and yesterday morning was 36.12 and this mornings was 36.50 so it’s gone up!

I’ve been doing opk’s since CD11 and have had EWCM a couple of days ago but none now....
