"my ob suggest mirena only because it wouldn&#039;t make me gain weight.  it went in on nov 2016 and the procedure was quick and not painful. i am 29 with two kids, c section both. i bled for almost 3 months. i kept calling the nurses and they kept telling to give it more time for my body to adjust. after 6 month i kept spotting randomly, finally 8 month into it decide to take it out, come to find out my uterus was inflamed and reject it and that why i was bleeding too much. i hope there is no permanent damage to my uterus."
