Those are all symptoms the Depo gave me. It took a month after I was due for a second shot and didn't get it for all of it to stop. I'd seek other birth control. Depo was also recently linked with causing problems with bone density. Talk to your doc about another option. My symptoms got worse before I was due for my second shot.

You could test to see if your pregnant. But a lot of those could just be from the birth control
