"i was recommended mirena after i got a blood clot at 17 years old due to a protein s deficiency, mirena was my only option. i decided after years of research that it was time to try it out. having never had kids i was told the insertion and everything would be a little more painful than a mother would experience (my mom was on mirena) the insertion was painful, but after i was fine. about 3 days later i was in so much pain that i kept throwing up and couldn&#039;t stand up straight, my gyno said this was normal... i&#039;ve had my iud in for 1.5 years, about twice a year a get pain like i did originally. i&#039;ve noticed mood swings, weight gain and total loss of any sex drive. only reason i&#039;ve kept it this long is it&#039;s my only option"
