It is normal to not have your period for more than 4 month while on depo?

It is not unusual for women to experience changes in their menstrual patterns while using the contraceptive injection, Depo-Provera. In fact, many women who use Depo-Provera experience a significant reduction in menstrual bleeding or even complete amenorrhea (absence of periods) after the first few months of use. This is because Depo-Provera works by suppressing ovulation and preventing the thickening of the uterine lining, which is what normally causes menstrual bleeding. While it's normal for your period to be irregular or even stop completely while using Depo-Provera, it's always recommended to consult with your healthcare provider if you have any concerns about your menstrual cycle or any other side effects you may be experiencing.
