What Are The Side Effects Of Using Depo-Provera?

I just got the depo shot yesterday before doing any research online. Now that I'm finally researching online, I'm seeing a lot of horrible stories caused by this shot. Now, I'm very worried about it since I'm stuck with it for the next 3 months. I'm wondering if there is some sort of statistics of women with each side effect so I can have an idea of how it might effect me. I understand that each person reacts to it differently, but having some numbers and percentages will help calm my nerves. Thanks.
