It is completely normal to experience withdrawal bleeding after finishing medroxyprogesterone acetate (Meprate). This bleeding essentially resets your cycle, acting like day one of a new period. You can generally expect your next natural period to arrive about 28 to 35 days from the first day of this recent bleeding. Whether it takes a full 30 days or slightly less depends on your body's natural rhythm, which can sometimes take a cycle or two to fully regulate. Please don't worry, as this is a very common response. If your period doesn't return after six weeks, feel free to consult your healthcare provider for reassurance.
