Hi there! You are welcome! Do you mean Depo Provera? According to ***** that drug should not be used with unexplained vaginal bleeding. In my opinion according to the site side effects can also cause bones to lose minerals maybe later causing a type of drug induced osteoporosis. I knew a woman who took that drug and she had all kinds of symptoms with it even though she liked it at first. Here is a site you can visit if you want to look at the side effects.
I know someone whose cycle seemed to be more regular with as regular a schedule as possible such as going to bed at the same time every night and many healthy habits. Also she liked the naturopathic medicine (not acupuncture which was useless and not chinese herbs which might contain more lead).
