Testing tomorrow - possibly crazy but I am CD 51

I am planning to test tomorrow. I am basically very irregular (average 37 days but have had longer), I’m currently CD 51, I have gone to 53 once over 2 years so generally this is very late even for me but difficult to say with certainty. I have low basal temps and I’m waiting for thyroid levels to come back.

My app thinks I ovulated CD 26 but I never had strong confirming opk and I often get ovulation cramps so I’m not sure, there also isn’t enough of a sustained rise and maintenance of my temp. There is however a temp change that looks promising much later at CD 31. This is really late, and I wasn’t opk testing unfortunately.

You might call me crazy, but I started using clear blue ovulation strips last week because I was sure I hadn’t ovulated. It kept flashing which shows oestrogen not LH, which can be high in pregnancy. For the past 2 days I’ve been having really low, almost fluttering cramping (not painful at all) which is different to normal pre AF cramps for me and by now I would expect spotting. I fully accept it could be cramps pre Af. However, my temp isn’t dropping in fact it’s rising.

I’m testing tomorrow which if I’m not crazy would be 13 DPO. I doubt it’ll be positive, and unfortunately I could only get a clear blue from the supermarket and I know they’re not that accurate. Will be testing with FMU. Fingers crossed 🤞🏻
