"i got nexplanon and my doctor told me in advance that its possible to bleed for 3 months but if it doesn&#039;t stop after 60 days, then you should remove it but if you can power through its worth it. i didn&#039;t bleed but my side effects were terrible acne and minimal mood swings (both can be managed.) now i absolutely love it as a birth control. it&#039;s the most effective form out right now and has eased my nervousness about pregnancy. i don&#039;t need to remember a pill or a shot or to take a ring out. i love it. the only cons are that it hurt when i got it in, and the amount of acne i got, but i think it&#039;s worth the effectiveness. 

sidenote: for 99% of others i know who have it, negative side effects stop after 2-4 months"
