"the insertion of nexplanon is very easy - i had bruising for a little over a week and very minor itchiness around the site, but nothing bad at all. since having it inserted in july &#039;14 my periods have definitely varied from non-existent to spotting to a full-blown period. when i have a period, it can last anywhere from a week to 2 weeks ... it may go away for a few days or weeks then return, or i have gone 6 weeks without a period only to get one for 2 weeks. it really varies a lot! if you can deal with the inconsistency, i highly recommend the implant. i have a history of depression and anxiety but haven&#039;t noticed any increase in symptoms for the past 14 months. my migraines have also decreased in frequency (the pill caused an increase!)."
