Are there any side effects from Depo-Provera (injectable birth control)? I haven’t had my period since I received my first injection one month ago. Should I be concerned?

depo-proveraThank you for your question! Most teens receive their first Depo-Provera injection during the first five days of their last normal menstrual period, which provides protection against pregnancy right away. If this wasn’t the case for you and you are sexually active, then it’s a good idea to take a quick pregnancy test. Although it’s unlikely that you are pregnant, it’s always a good idea to double check.

Depo-Provera is known to cause lighter periods and/or no period at all. And it’s completely safe to not experience a monthly period if the missed period is caused by a hormonal medication such as Depo-Provera or other birth control methods. The risk for pregnancy is less than 1% if the injection is given at the right time. However, Depo-Provera won’t protect against sexually transmitted infections, so it’s very important that you use a condom every time you have sex and get tested with any concerns. It’s also a good idea to share any questions or concerns with your health care provider (HCP) to ensure that Depo-Provera is the right medication for you!
