Had the mirena coil fitted just over a year ago now, and wanting to have it out. The first couple of months of having it in i turned into a monster, i was constantly in a bad mood and would tear into anyone for no reason at all and that aint me as i am very laid back. This then calmed down and i returned to normal, and now every now and again every time me and partner had sex i wouldn't be able to move due to awful pain felt like the coil had pierced my wall or something, this would die down after a couple of hours and a packet of pain killers, it hasn't happened for a while thank god but now i am getting constant period like pains. I have gained 3 stone in weight and gone up 2 dress sizes and i have upped my excessing and diet but its just not shifting at all and i seem to be getting more headaches and my boobs just don't seem to stop growing. Although my skin is acne free as it has never been and i have had no periods for nearly a year now which is nice. But i have had enough and want it out, i want to feel normal again.
