I had my mirena put in 6 weeks pp in 2005 everything seem to be fine for almost four years with the exception of an ultrasound which i found out i had almost fifteen cysts on one of my ovarys. For the past three months i jog three miles a day and other cardio and in 12 weeks I have only lost three pounds but quickly gained it back. I even went on nutrisystem and ca not lose the weight i have it scheduled to be removed tomorrow Nov. 7 I hope I am not making a mistake but I to also have severe anxiety and cramps from my cysts in all the main thing is the weight gain since I had it put in have gained over 30 lbs I am just wondering if the weight will come of quickly...
