I got my Mirena about a year and a half ago. I've noticed that my body seems to "think" it's having a period multiple times a month. I'll notice that my uterus has moved up the way it does when I'm about to start a period (I'll look bloated) and then a few days later my stomach is flat as a pancake and then 10 days later the cycle repeats. Has anyone noticed this? I feel like my body is completely confused.
