birth control
"I had the IUD insterted in March 2015. My doctor had me wait until I was on my period so that my cervix would be "spongier" and wouldn't hurt less. Unfortunately for me, because I had been on birth control for 4 years prior, I was having an extremely light period. Easily the most painful experience of my life. Was doing all I could NOT to scream in the examination room during the procedure. After the procedure I had to lay there for a while before being able to get up and leave.  The pain lasted the entire day. Very sharp throbbing pain. I aImost threw up twice. After a few days I was fine. My next period was very painful, but got lighter as time went on. I'm very happy with this IUD, I'm not sure if I will replace it though due to the pain"
