Typically, a withdrawal bleed occurs within 3 to 10 days after completing medroxyprogesterone acetate (Meprate), but it can sometimes take up to two weeks. Since you have confirmed you are not pregnant, the delay might be due to low estrogen levels, which means the uterine lining didn't build up enough to shed. Other factors like stress, hormonal imbalances, or thyroid variations can also play a role. I do recommend reaching out to your gynecologist so they can evaluate your hormone levels and guide you on the next steps.

What does it mean if my period has not started 10 days after completing a 10-day course of Meprate, and I am not pregnant?
