Moms! Any of you on the Nexplanon birth control? How have you liked it? Any side effects? I just recently got on it because I had some medical issues & with that being said I can't get pregnant for a whole year. I couldn't get the IUD's because they didn't want anything in my woman parts because that is where I was having the issue. Anyways so my doctor said that would be the best choice. It's been 2 weeks & I was okay until yesterday. I have done nothing different & I almost couldn't get out of bed. My back pain was out of control. I have never hurt that bad. Today I'm back to normal? I researched the Nexplanon & saw that one of the side effects is back pain.. has anyone experienced this?
