my advice to you would be to speak to your gp, i was on the depo and waited and waited for a period to come, in the end i went on the pill to try and start a cycle again. in actual fact this didnt work either for me as i have pcos and the only way i get a bleed is from provera induced bleeds, but perhaps if you were to take the pill for say 3 months, that could get your cycle going again?? Speak to your gp, hope this helps.
