I started the nexplanon October 22nd and have had no issues and now am having acne, nausea, headaches, tender boobs, vaginal discharge, some abdominal pain and a very high sensitivity to smell and ive been getting car sick some are normal symptoms of the birth control. Has anyone else had all these symptoms and not been pregnant. Have you or anyone you known got pregnant while on nexplanon? I know it says it 99.9% but it also says they dont know how it effects overweight women which i did not know till after i got it. Also smelt cigerette smoke this morning and made me sick :-/
