Puppies symptoms and conditions

I had my first baby Nov. 4th, 2008 and got Mirena Dec. 25th, 2008. I did not want to be on the pill again because I never had an orgasm until I came off of it (sorry if TMI). I had a c-section, so of course my belly was sore for a while. I had lots of light bleeding for weeks after insertion and then it stopped. Now, I have been bleeding lightly for over a week again off and on, and my belly is sore inside. I don't know if this pain is from Mirena or from my internal incision? Also, if I insert my fingers I can feel something inside me (the string maybe?). My husband complains of this "poking" him during sex. He says it feels like a pin. I DO NOT want another child, not at this point anyways, but I don't know that this Mirena is for me. I should just get my tubes tied, but what if I decide I want another baby down the line?? This is so confusing for me. I really don't want the hormones and chemicals from BC again. I also have to take several mood-altering meds because I have been on a rollercoaster with my moods. I had depression problems my whole life, so I didn't associate it with Mirena until reading your posts here.
