I have had mirena since oct 2007. i have had a lot of problems since. i have just recently the past 5 months or so, been able to loose any weight! i actually gained 15 lbs after i had it put in. also it had rejected itself the first time after about 6 months. and the main reason i started searching today on here is because for the past 3 weeks right after my last period, i haven't been able to find the string. i can completely feel my cervix because im short spaced. there is NOO string hanging out and i have had serious cramping. about a week ago i was standing at my microwave and all of a sudden i started having a lot of white/clear discharge leaking down my leg.. i wasn't sure what was up because i was also having some cramping. i figured i HAD to be ovulating. so i took an ovulation test and i was right! i was ovulating. 4 days later i took another test after the discharge went away and it was neg. i called my doctors today because ive been having a lot of bad cramping. she told me you do NOT ovulate while u have the mirena and the test should never had been positive. she said the string can go inside my cervix but it wouldn't cause any cramping but she said if the mirena was moving or shifting, she said i will get a lot of cramping and it can be dangerous. im nervous and she said if the cramping gets worse to go to the er. she said tomorrow i need to have a pregnancy test and an ultrasound done. i am nervous and i want this thing out of me!! when i touch my cervix, i get sharp pains. the same pains i had when i was dilating with my daughter. this sucks!! i will also agree with others.. the weight gain/hard to loose is deff something that has happened, still breaking out, more cramping when bleeding, mood swings, i STILL lactate after over 2 yrs of stopping breastfeeding, i still am VERYY sensitive and cry easily, my lower back hurts all the time, always tired/lazy, i feel pregnant still!!!! i prolly have every symptom u could think off. another thing i want to know is.. can the mirena make it so i can get sick more easily...? like lowering my immune system?? i get sick with a cold or nasel infection or fevers or something everyyyy month!! i am ALWAYS sick!! ive had strep throat prolly 6 times in the past 2 yrs. fevers prolly 5 times.. im sick as we speak with a nasel infection, wooping cough, diarea, sleepyness, head ache... and ive been sick since 10/20/09 and its 11/9/09 today... no fevers so i know it isnt swine flu.. but damn! im always sick!! ever since i had my daughter... which is also around the same time i had the mirena put in... welll... theres my story... mirena needs to be taken off the shelves and if anything happens to my cervix or makes it so i cannot have kids, so help me god ill sue the livin shit out of them!!! yaz got sued... mirena should be too!!!
