I am a 25 y/o mother of 5 boys, and my youngest is 8 months old now, and I had mirena inserted in Jan. 2009. I also I have lupus, so my hair falls out when I am pregnant or breastfeeding, but I delivered in Nov. 2008, and stopped breastfeeding in May 2009, and since I quit breastfeeding, my hair falling out has only gotten worse. The first 4 months that it was in, I had a heavy non-stop period. Now I get a 7-8 day period twice a month. In between my lengthy periods, I have a discharge that smells really weird. My partner tries to be understanding, but it's difficult for him I know. He says I have permanent PMS, and that I'm pushing him away. My mood swings from happy to sad to out right angry at the drop of a dime. It's kinda scary really, especially since I work around people and can't afford to have a break down out of nowhere. My partner also said he can feel the threads from the mirena sticking him when we have sex, and that it hurts him. On top of that, whenever we have sex, I always start bleeding for a couple of days (2-3) w/ real bad cramping. I have also had weight loss instead of gain, I get body chills, nausea, irritability, and the list could go on forever. I also had a bad experience w/ the depo shot, and I'm not good w/ pills, so I am looking for another form of birth control that isn't permanent because we would still like to try for a girl one day, just not now .... HELP ME!
