Does anyone take metformin to try and help regulate ovulation/period and track their cycles with opks?

Before I started taking metformin my opks test line would usually be pretty dark, I’d get false positives and what looked like multiple LH surges. It was consistently mid-to-dark test lines throughout my cycle.

I’ve been taking metformin for a couple of months and noticed this cycle that the opk test line has been super light and consistently light for days. This is super unusual for me! Does this mean my LH levels aren’t as crazy now?
