No period for a month '13, prescribed medroxyprogesterone & period started. now not ovulating (per kit), i take levothyroxine 88mg, ok to take vitex?

Complete evaluation: If you mean vitex agnes castus (chaste tree), i would be sure to complete the evaluation for why your periods are abnormal first. Thyroid disease can affect periods, but other things can as well. You have already had Progesterone causing withdrawal bleeding, so it sounds like an estrogen problem. Vitex will not usually adequately treat that. Be sure all medical problems are addressed.

See a physician: There are many reasons why women have irregular cycles uncontrolled thyroid disease is only one reason. Since this appears to be going on for awhile (i.e. You needed Provera (medroxyprogesterone) to start your last period) you will need a full evaluation to determine the cause. I would not recommend adding herbal therapy until you have seen a physician.
