Good day doctor I have been using the three months Petogen injection for four and half years now, the first 6 months of starting to use it I was using nuristrate and it span my periods out of control I bled for more than three weeks every month and they changed me to start using Petogen which I want to stop to using now. I have been bleeding but its been tiny drops and towards the end of the third month i bleed for a day or two then it stops. Does this mean that my homones are too strong for the nuristrate injection? I would also like to know how long would it take roughly to get it out of my system or my body clean of the injection again should I want to start planning to get pregnant?
