Levonorgestrel
"I have had the Mirena in for close to one year now. I have one son and my husband and I have been talking about having another child. Around eight weeks ago I started having horrible mood swings, crying, and I have become very easily upset.Weight gain, low libido and continued dryness are also a problem. I have unbearable cramping and pains in my lower abdomen, and I have had 6 yeast infections since I had Mirena put in place, I had never had one prior to this. At first I put all my problems up to working on the Noc shift, when I quit doing that and the signs were still there I realized what the problem was."
