I've posted my side effects in July and I'm scheduled to have it removed next week. I"ve had mood swings, cramps, no periods except some spotting, weight gain, extreme fatigue, dizziness etc. Does anyone else have "good" days - days that you that you have no cramping, you're in good mood, no fatigue? I wonder if the Mirena releases the (progesterone) levonorgestrel unevenly throughout the month? Some days I feel really good and think the side effects must be in my head and then a few days later I feel like crap again! (The Mirena website says it releases 20ug of levonorgestrel a day). I felt good the past few days, I had more energy. Actually got some stuff done around the house. Today I woke up and I feel dizzy and sharp pains in my abdomen.
