Natural period after 8 years!!!!

I was diagnosed with PCOS when I was 14 (20 years ago) Back then, the answer to my PCOS problem was birth control. No testing, no information, no other medication or insights as to how to treat my PCOS....just BC. My period was regular for years due to the BC. But when I turned 22 I stopped taking the BC to try and get pregnant with my husband. When I stopped BC, so did my periods....besides the occasional 1 or 2 per year...then it gradually tapered off to nothing at all. Then when I was 28 about to be 29, I took the step of getting ALL the testing, and seeing ALL the specialists. From age 29-32, I had forced, Provera periods which I consider "un-natural" and it was only to try and get me to ovulate so i could get pregnant. After 4-5 of trying everything except for IVF(insurance wouldn't cover it), i gave up. Periods stopped all together and I went into a long depression. It wasnt until this year I decided to do my own research and figure out what I could do to reverse my PCOS naturally. I made the choice that on my birthday (June 1st) of this year, I would do the diet and exercise and also take the recommended supplements that are proven to help. So when my birthday came, I started it. But to my surprise....on June 4th, I started my period!!!! How? I have no clue! Considering I literally just started my life change on the first. So that means that 2 weeks or so ago, my body decided to regulate its hormones enough for me to actually have a NATURAL period after 8 years!!!! I'm accepting this as a miracle, but I cant help but still wonder HOW!?!?! Does anyone else have any insight on this? Any info at all would be greatly appreciated!
