"i have had the nexplanon since february 2015. in september 2015 i had all the symptoms of pregnancy. took all the test and the were negitive. i have had mood swings since march 2015 and they are getting worse. someone could say something to me and i start being a horrible, cry or not feel anything. i have severe headaches and nothing helps. they are so bad they make me see double. i found out today that i have to find a new dr because my insurance is no longer accepted where i live. i have to change it or drive almost an hour to see one. i do not recommend this product to be used. please stay away and find another birth control."
