It is very common to experience brown or light red discharge after taking Deviry (medroxyprogesterone acetate), as your body adjusts to the hormonal changes. This is a normal response to the medication. Typically, you can expect your withdrawal bleed, which will feel like a normal period, to start within 3 to 7 days after taking your last tablet, though it can sometimes take up to two weeks. Please try not to worry, as this is your body's natural way of resetting its cycle. If your bleeding becomes very heavy or you experience severe pain, please consult your doctor.
