Levonorgestrel
"I had this put in about 6 months ago after I had a miscarriage due to the type of blood I have. Anyways, I have had it for a while now and didn't have any problems with it until now. I have been having my uterus contract as if I were having another miscarriage for the past month and a half now. I have to take 5 ibuprofen every morning to even wake up feeling okay, and now I am pretty sure that I have a ectopic pregnancy and if so then that means I am going to lose another baby. I HIGHLY don't recommend it."
