Does the Depo-Provera birth control shot prevent implantation of an embryo possibly causing a miscarriage in first week after conception?

Depo-Provera (medroxyprogesterone acetate) is a hormonal birth control injection that prevents pregnancy by thickening the cervical mucus, thinning the lining of the uterus, and preventing ovulation. It does not prevent implantation of an embryo.

Therefore, it does not cause miscarriage.
