I was kinda forced by the doctors into getting the Mirena about 2 months after my son was born. I was so overwhelmed with being a new mom that I did not research it much. Getting it put in was no picnic. I have had is since 10/08 and had it removed this past Monday. Within 1 month of having it put in, I put on 15lbs. I have been and am still breastfeeding so my doctors said it would help me lose weight but I gained instead. Nothing else in my diet or anything had changed. I know having a baby not sleep through the night will make you tired but I was an undescribable tired for the past few months. I have also been moody and negative - my mom kept saying she needed me to "smile" again as I am normally a happy person. I plan on TTC for another baby in about a year so I really want to be as healthy as I can since I will have my son to chase around. I talked to my doctor about all this and he agreed that it was probably the Mirena that caused the weight gain. I am worried about the "crash" people talk about after having it removed. I am hoping since I just switched from Prozac to Wellbutrin (for mild depression & anxiety issues) that it will help. I know Wellbutrin sometimes help with weight loss as well. The past week I have read a lot of forums online and it seems people are having similar side effects...oh did I mention the foggy thinking? I wish they would have told me all the issues prior to putting it in. I never would have had it put in or had it removed even sooner
