Aussiegirl, Oh my Gosh YES. I have been scared to ask this and thought maybe it was unrelated but yes, I have bruises all the time and I have no idea where they came from. I was on a blood thinner for a year and didnt have any bruising but since I went off the blood thinner I have tons of them. Mostly on my legs. I wonder if that is a hormone imbalance symptom. I have been so scared but it makes me feel better to know it could be from mirena.
