hi i had my mirena fitted on 30 september. i was bleeding at the time. i have no kids and ive had lots of trouble with periods and constant period pains endometriosis etc. it was nowhere near as bad having it fitted as i thought i just took a couple of painkillers beforehand.i am now on my 25th day of bleeding not much most of the time and i am still getting some cramping every day and still taking painkillers .SICK isnt the right word. my boobs are constantly sore. my friends gp has told her i should never have had it fitted when ive had no children and without them first giving me a blood test to check my hormones as i had fertility treatment years ago. i have a lot of trouble losing my hair which is bald at the back which i use steroid cream on to make it grow back and he thinks all my problems are linked to hormones so the coil wont help. ive had 2 laparoscopie and a major op to deal with my problems as well. going to change doctors tomorrow and see what he says about it all.
