"The only reason this is rated a 7 is because of the effectiveness. I started with the implanon version for about three years; it was great with an occasional bad cramping. I got the next one, nexplanon, and have had it about two years. The cramping is horrendous at times, lasting two weeks or off and on regularly. My periods became a majority of the month by the second year of having nexplanon. I have always had anxiety but I personally feel that the nexplanon is making it worse and I was diagnosed with IBS (for the pain and stomach upset/anxiety). A part of me is terrified that if I take the nexplanon out my symptoms will get worse, but I can also tell you I've never had these symptoms until I took Nexplanon. Be wary."
