"i got on nexplanon october of 2015 and was fine at first. i had a regular period the first month on it, just my normal 5 day-ish cycle. and i haven&#039;t had a period since. buuuuut, i am bloated 24/7 (maybe due to not having periods?? idk). i have gained weight.... like 35-45 pounds. i have mood swings from hell! one minute i&#039;m happy then the next i&#039;m crying and the next i&#039;m angry! of course it&#039;s effective because i haven&#039;t gotten pregnant, but the mood swings and awful weight gain have made me miserable. i do not recommend. i should have stuck to the pill!!"
