"i have had the nexplanon since oct. 2014. i loved it at first - i was so excited that i could be on a birth control that i didn&#039;t have to worry about taking daily and also make my period lighter, shorter, or even non existent. i was very concerned when my gyno said that it could cause some spotting but very rare. i definitely should have done more research because based on all these reviews it just shows that everyone has a problem with there periods being more existent than ever before. i have my period for 8 days on and then 8 days off. literally every other week. i&#039;ve also gained at lease 5-10 lbs of weight. i&#039;ve been 10 x more moody. my face has never broken out like this before (it&#039;s aweful) pimples in places i&#039;ve never had."
