Pcos and metformin

I just recently started taking metformin to regulate my irregular cycle since we are ttc. Was wondering if anyone had more experience and could provide some insight!

How quickly should my cycle regulate?

Has anyone had crazy bad bloating from metformin use?

And nausea?

And for those of you that didn’t conceive on metformin, how long did you try before trying something different?

My husband is a little older than me, and we have tried for 5 months before taking the medication route. I don’t want to wait too long, but I also know stressing over it too much doesn’t help! Ah!! Stupid pcos!
