Ovulation questions-opinions wanted!

Hi friends!

I'm currently in month 12 of TTC after MC. So far I am on CD 15 as of today (my cycles vary from 29-35 days.. sometimes more of I'm stressed out) and the closest positive opk I had was yesterday and today it's definitely negative again. I'm also temping and I feel like it's been kind of all over the place, we are having a huge heat wave here in NE. I've posted my temp graph and my opks and I wanted to see if anyone had opinions on whether or not I've ovulated or not. I think yesterday's was negative as well, but I want to be sure. My husband and I have been BD'ing every other day so 3 nights ago and last night. I may still ovulate later in the month, last month my pos opk was cd 13 and then another one on cd 18, super weird. Period started almost 2 weeks after the 2nd opk. Anyway, please feel free to comment! It's SO appreciated! 💜
