UGGG!!!! You all have helped clear up my confusion. I had my mirena put in July 2008. I didn't seem to have any adverse effects...at least not anything big enough to question the mirena. I had acne and a little weight gain, and then my knees started hurting. Then over the last month I started getting this stomach!!! It's huge!! I look 6 months pregnant. I also noticed that I was getting a lot of headaches, and extreme mood swings. Then it got harder and harder for me to read the TV from the couch. I was wondering last night if I should go get my eyes checked. I also find myself wondering who has taken over my body. I get all angry and mean!! I can't believe the stuff that comes out of my mouth, and my husband is looking at me like I've lost my mind. I feel thirsty all the time, and I have dry skin and chapped lips a lot. I've also experienced constipation, chest pain, pain in my right breast, extreme abdominal pain, like when you ovulate. After I got it in I bled for a month straight and I haven't bled since...not one period. I thought it was a perk, but now I feel so strange. It's like an out of body experience. I also struggle to find energy for anything, I'm tired all the time. I feel like I'm falling apart. I had to pay for the mirena out of pocket because it was the beginning of the fiscal year for our insurance, and so I(because of the expense) decided I should leave it in. I appreciate your comments, no amount of money is worth what I'm experiencing!
