"i have been on nexplanon for a little over half a year and it&#039;s awful! ever since i got it in my arm my periods went from 7 days and regular to bleeding all the time and irregular. when i wake up in the morning my breasts are hard and they are sore all the time. i liked the fact that i didn&#039;t have to take a pill but this is so much more of an inconvenience. i feel like i have several of the side effects and cannot wait to get it removed. i wish i had read the reviews before..."
