Well, there you go. It has started working already.

You have to keep in mind your body did not get all messed up within three months, so it will take a little longer to regulate it again too. It happened slowly for me as well, so have patience.
Since you're asking exactly how long it took, well, let's see. I had been skipping af and then missing af entirely for almost a year when I started on Met. Af came back within a month, cycles were fairly regular. I lost some weight (was low-carbing too). It was eight months (I believe) until I started ovulating again too. Somewhere in between, more towards the beginning I started actually 'feeling better' too. I went from 'hormonal monster' back to 'normal', and it was a good feeling.
I think Met is just the greatest thing ever.
