birth control
"I had the Paraguard IUD placed about a year and a half ago after the birth of my fourth baby. Insertion was uncomfortable, yet not painful to me and my cramping was minimal and lasted about through the evening. Shortly after insertion (within the first month) I noticed a lower back ache. The ache progressed into a sharp pain that made me very careful about bending over or picking up my kids. This pain has lasted the entire time I've had my IUD and during some points in my cycle, its unbearable and nauseating: ( I've tried to be patient, hoping that the back pain would dissipate but to no avail. I'm scheduled to have it removed tomorrow and I'm going to try another method. Also, my IUD caused a crazy discharge all cycle  long !"
