Hi, I've had one little one and have almost had the mirena in for a year . The first few months I bled non stop then they evened out and became regular . I've had spotting a couple days before starting but this time (it's been about 3 weeks since last period) I have been spotting for a week straight - all brown . And nausea in the evenings the past 3 days . Can anyone tell me why this is ? I've read spotting more than a couple days isn't normal ???
