I had Mirena inserted just last week and I was searching for side effects on the internet to see if my bleeding is normal that I am having. I see now that it is, but I do know if I keep bleeding for a while I will have it removed. My friend got Mirena and said oh you will love it, I have two children and do NOT want anymore and my husband is scared to go get snipped so I thought this is a good option. Well, hopefully my bleeding stops soon, its not heavy just kind of like a discharge at the beginning of your period, but if it gets heavy or lasts forever I will reconsider. I feel great otherwise and the bleeding is not really a burden but we will see. Maybe I should have read this site before having it in place, I don't know , hopefully I don't have any real problems with it.
