need thoughts and opinions!!

I am irregular, the last 3 months my cycles have been 27, 41, and 40 days. last af was August 26th so I am on CD 20 now. I have been taking opks and have failed to get a true positive yet. but, the test got darker on CD 12 (just not darker than control line) I had cramps and a ton of ewcm the 3 days prior, spotted pink on CD 13, cervix was SHOW, woke up the next day and had no ewcm, and all symptoms of ovulation vanished. now I have cramps again, opks are getting darker (almost as dark as my test on CD 12), very little creamy cm but hard to tell because of semen lol my cervix is medium in texture and medium/high. I don't think I'm going to ovulate but my breasts have gotten bigger (as my husband delightfully announce

)I'd love opinions on when to test and if you think i could be gearing up to ovulate with out any symptoms since the test is getting darker again. we are still bd every other day to be safe but I don't want to get my hopes up that I might be pregnant if I haven't even ovulated yet 🤔😣😑
