Right? Lupron comes in daily, one month and three month formulations. Luron does stop ovulation but shutting down the signal from the brain to the ovary. Lupron is pretty good about doing what it is suppose to,,meaning a daily dose last a day, a monthly dose last a month and a 3 month dose last 3 months. I would not count on it going longer than the time alotted but not a lot in the shorter range either. When the duration of the formulation given is over, most people go back to their cylce pattern before lupron rather quick, maybe a one month wash out of your system. If you were irregular before then irregular after, regular before then regular after.
HOPE THIS HELPS
