I was wondering if you could help me please. I'm a 26 year old woman that has Endometriosis. I usually have the most severe periods that not only cause extreme pain, but excessive bleeding. Since having the mirena, I have found that it did make my periods a lot lighter, but I was still experiencing all the other symptoms. It has been 3 years now and out of nowhere, my periods have suddenly stopped. I have had 9 months now without one. I have been to the doctors and all hormone blood tests came back normal. I am, just a little concerned as from reading up on this issue, I couldn't find anyone where it took this long? Is this normal for it to take 3 years to work or am I being 'fobbed' off by the same doctors that took 8 years to find my Endometriosis. The doctor is happy to assume that it is just the effect of the mirena coil, but I am unsure??
