I just used the "Search Site" window at the top of the page. You can check things out there to get info from past posts, as these questions come up frequently and there will be more dialogue to look at there.
IMHO you are playing with fire if you try to manage the reporductive hormones you've mentioned on your own. This requires a real skill and lots of repeat testing to make sure you don't really fowl things up.
It takes a lot of time and patience to work through all the issues that we have sometimes. Your GYN would be a good place to start since your cycles are difficult and that doc would have training in assessing and balancing those hormones.
I know I'm not much help and you are anxious for some relief. Hang in there!
