Ive had the Mirena in since Dec 2006. It was going great for me too at first then i starting piling on weight significantly and i got cramps and now 2 years later i have sore lower back,tightness down there,weird feeling when i pee at the mo(bleeding and all too),cramping,heavy bleeding!!!!!!, and i also thought i had symptoms to do with pregnancy as well (just like when i was carrying my daughter but the docs rekon you cant get pregnant on this, just like the side effects). I got this put in me as im very low in iron and bleed heavily otherwise. The doctor told me this was the only one that had NO SIDE EFFECTS. Im going to the doctors next week to find out why i have been bleeding the last 2 MONTHS and have huge blot like things coming out too :( Maybe i should go by my own instincts next time and not a doctors. they don't seem to know everything.
