Need some advise about pcos and metformin

I’ve been on it since January to regulate my cycles. And I would have to say at first it was hard remembering to take the medicine regularly. I missed a bunch of times. But in the last two or three months I’ve been religiously taking this medicine along with my cabergoline. So a good 8 months I’ve been on it for the most part. My cycles were normal even though I missed a few times of taking the dose.. and now this month I’m two weeks late. some times I am a week late. But even then I would get some signs of my period about to show. Especially sore boobs and pimples. Right before the period I get emotional too. Well in these last two weeks I have no signs of my period. She is MIA RIGHT NOW!

Is there any one on metformin for PCOS? Let me know your story. I’m very curious...
