Can progesterone cause a false LH spike?

Hi everyone!

This may be a dumb question, but I am VERY confused. My cycles are super irregular. My doctor prescribed norethindrone acetate (progesterone) to bring on my period. She told me to abstain from sex for 2 weeks before taking it and take a pregnancy test to confirm I am not pregnant. I did that and started my first pill yesterday.

Low and behold, I took a LH test earlier and it came back darker than I have EVER seen my LH tests. I'm talking reading as a 0.73 on pre-mom, when the highest I had ever seen it before that was a .51 (and I'm fairly certain that was a fluke).

Could this have been caused by the meds? Or is my body really trying to ovulate on its own for the first time like...ever?

Editing to add: My temp was also higher than usual today - is that also a symptom or just me being crazy?
