There are lots of great herbal remedies and ideas on this forum if you read through the archives, you will find them. The only issue and probably why no one has answered you yet is that there are some concerns with using meds and herbs together. You are using Provera to induce menstruation and then if you use herbs to try to balance your cycles your body becomes confused with the mix. It can be counterproductive. It may even be dangerous. If you are going to continue using conventional medicine then I would highly recommend you consult with a naturopath about how to integrate the conventional and alternative treatments safely and productively.
Good luck,
