need help...

So I have an issue. Not sure where to go for advice here. So I do believe I'm 10dpo maybe 11dpo. I got what it thought were postive opks on cd 16 and cd 17 I stopped after cd 21 after the line basically disappeared. I work graves so tracking with opks has been really hard. This is my first cycle of fermera. I had cramps on both of those days. So I assumed that was a good thing sense it's never happened before. I took a test today on 10dpo today at 4:30am and it was negative. My last pregnancy I had a faint on 10dpo. I'm curious if I'm out this cycle. Does anyone have experince with TV and night shifts. This is very new 2 me. Did I even ovulate? I just need advice. 5 years ttc, 9 Mc and going through a terrible divorce. I need this to be my time :( pictures of opks and 10dpo test.
