What Are The Side Effects Of Using Depo Provera?

Hi I'm 20. I had a bby in Feb 09. Since then I was on the depo shot until July 10. I started noticing intercourse was a Lil on the dry side for me in Nov 10. My question is if my vagina became "less lubricant" will it remain dry or I have to wait until the depo wears out of my system ?
