Chart (I use Glow, please don't hurt me)

I posted 10 days ago on TFABLinePorn asking if any of my OPKs looked positive. I also posted my chart so people could interpret. Everyone said it didn't look liked I'd ovulated, so I kept tracking and we kept BDing. On the night of CD31 and morning of CD32, my OPKs were darker than they had ever been and I was pretty sure they were positive, so I changed all the others to negative and recorded the positives. I also had cramping, tons of EWCM, slight nausea and I even thought I felt a "popping" sensation. The OPKs in the morning and afternoon of CD33 were significantly lighter, the second one was lighter than most of the other ones through the whole cycle. I hadn't seen a drop like this with what I thought were the other surges. My CM got drier too. My temperature doesn't seem to be going up like I thought it would though.

For reference I'm on my 6th cycle since going off of BC. My previous cycles were 30, 39, 34, 39, and 46 days. This is my first cycle of serious temp tracking. I temped inconsistently last cycle but I did do most of the second half of it and around this time last cycle my temps went up from low 97s to high 97s/low 98s.

Thoughts?
