HELP!!!

So little back sorry I have always had irregular cycles but my fertility specialist got me put on 2000 of metformin a day ( for pcos, and insulin problems) about a year ago and I finally had regular cycles!!

Now my cycle is irregular again!! I got a positive opk like I have been for the past 8 months or so and I’ve had no cycle... has anyone felt with this?

Pregnancy test from home are negative.
