question: I have had the mirena iud for 3 months with approx 6 days of no bleeding here and there. Mostly its been a tolerable spotting, for the past week I have been on a heavy period which is becoming lighter. Although Ive had clots throughout the periods today I have seen a somewhat large size the length of a small tampon. Should I be worried? I have also been becoming lightheaded when I get up from laying down or sitting down in my own mind I think this is maybe anaemia?
