Depo-Provera (a progesterone-only contraceptive injection) is generally safe to use while breastfeeding, and it does not harm your baby or affect breast milk quality. In fact, this type of contraception is often preferred for nursing mothers because it does not contain estrogen, which can reduce milk supply. It is usually started after 6 weeks postpartum, so at 2 months after delivery, you can use it if there are no other medical concerns. Some women may notice mild side effects like irregular periods, spotting, or delayed return of normal cycles after stopping the injection, but these are usually not harmful. Before starting, it is still important to consult your doctor to confirm that it is suitable for you based on your health. Overall, Depo-Provera is a reliable and convenient option for contraception during breastfeeding.
