Increased vaginal discharge symptoms and conditions

I got Mirena inserted back in April 2009 after my son was born. I have been feeling tired and have had back aches as well as some increased vaginal discharge. However, no foul odor and my sex drive is just fine. I'm wondering if the effects get worse the longer you have it in? It seems that most of you are experiencing these horrible side effects after 6months or so.
I'm going to keep my Mirena in and see how things go. It is a convenient form of birth control, but since I no longer have a period I get very paranoid that I could be pregnant again! :\

I had Mirena inserted one week ago and there was some minimal cramping directly after the insertion but I have had nothing ever since and I am hoping it remains that way. I am so sorry to hear of all the negative side effects that Mirena is causing some women but I am interested in hearing some of the more positive feedback.

I am so depressed and sooooo sleepy. Breast tenderness, increased appetite, increased vaginal discharge which ITCHES LIKE HELL. And this thing is always sliding out. I am sick of sticking my hands up my vagina every day. I hate this thing. I am taking it for PMDD and all it is doing is giving me PMDD symptoms 24/7 instead of 2 weeks/month.

The doctor told me to take B vitamins to help eliminate side effects. The day I didn't take my B vitamins I was even more depressed, so maybe they can help you. But I think this Nuvaring is horrible and am really tempted to rip it out instead of waiting to see if the side effects go away.
