So, I got my first Depo shot, June 27th 2012. I wasn't supposed to start my period until July 23rd, But I started it 2 weeks early on July 9th. I've heard that the depo shot makes your periods last a lot longer. I'm on the 7th day of my period and it doesn't seem like it's going to stop anytime soon. Any advice on how I can fix this problem?
