I had the mirena coil fitted 2 weeks ago now! never had children, only 21, by the way. After 7 days of having it in, I ve had thick brown, redish discharge. In pain, in abdominal area, like a really bad aching pain. Its been going in for a week now this, and I have no sex life with my boyfriend, I have put weight on as im eating more as I have craving, weird as I have never had them before. But the pain and constant discharge/bleeding is causing me discomfort! Im wanting to know if this is normal? but im getting fed up.
