I had my mirena inserted 5 years ago and is du to come out in two weeks, I had surgery for endometriosis and my doctor advised me to get one inserted at the same time. I gaided 20 kilos when I was 20 from the illness and have gained another 20 kilos since surgery. I am 26 and sick of the weight gain, seeing this site has given me the courage to go with out it. I will be telling the doctor I do not want another one.
