Wow, you poor lady.
Seriously look into the herb vitex. I had pcos about 10 yrs ago. That was when I was overweight and not really healthy.
After some time I lost a lot of weight and really started getting into eating right and taking vitamins.
After so so long I found this herb vitex that I started taking because even after having lost a lot of weight my periods still were not regular. It took a few months at least to get back to normal.
I don't take it anymore now and haven't for a couple of years. I'm in shape now and eat good and get exercise and am very normal thankfully.
Of course, I don't know if you are taking medicines or anything, but as with any herbs you think about taking it's a very good idea to look into whether it would be safe for you to take.
I never went to a doctor or anything. I just followed how I was feeling and went along with what I felt was right.
I wish you the best!
