Any thoughts on my BBT chart?

For what’s it’s worth I have a work schedule where I go in at different times of day so sometimes I’m up earlier or later so temps are not taken at the same time. All temps are taken with an OvuSense.

I recently started 25mcg of synthroid for high TSH levels. I also have elevated testosterone, but have not been formally diagnosed with PCOS.

My period was supposed to start today. I’ve been cramping but no other signs of her or not. I’m worried I didn’t actually ovulate at all. I was using OPKs but stopped after CD16 because I hadn’t been getting anything close to a positive and was getting discouraged.
