"i had the nexplanon inserted in may 2015, the insertion was quick and easy. for the first few months i had a regular period but it got shorter each time. last month i had it for a total of one day and this month i haven&#039;t had it at all (which is scary at first because i thought i was pregnant) but my obgyn told me i would havery irregular bleeding or spotting and then it would eventually stop and i think it did stop but i still get occasional spotting but it&#039;s not bad at all. i do get bad mood swings and depression sometimes but it&#039;s nothing serious. i also am very sexually active and this birth control is amazing, i haven&#039;t gotten pregnant yet so it&#039;s definitely almost 100% effective.  would definitely recommend."
