Ive had this damm thing inside me for a little over 18 months and since I have had it in I have gained 2 stone in weight ..... my eating habits certainly havent changed and I now exercise more to compensate for the weight gain, but nothing, the scales do not budge, initially putting it down to me getting older (40 now) but then I started having terrible stomach pains, lower back pain, headaches frequently, at least one a week. For me the worst point was my cup size going up from a C to a FF, which I am struggling to cope with now ... I hate them being so so big and so very very tender, especially my right one ... I find that even when someone brushes past me I wince. One other side effect that I hate is sex is very painful now. I have been back to my doctors with all these symptons and they have sent me for numerous tests - all back negative, I might add. It has got to the point where I thought I was actually imaging it all. I have mentioned it to 4 different doctors at my surgery saying could it be down to the Mirena, but I was dismissed by all of them with a resounding NO WAY.. and I was made to look foolish. I am having this monster removed ASAP.
