"i got the nexplanon after i had my daughter in 2014. i bled constant for eight months straight. i then went to sporatic periods (on one week, spot the next, nothing a few days, then bam back to bleeding)  i have gained 30 pounds on this and can not lose it for the life of me, no diet or exercise regimen will work. also, i have been battling depression and dissociation off and on since i got it. however,  i haven&#039;t gotten pregnant. so it definitely does it&#039;s job. but i finally am scheduled to get it out next week, one year early. i will not ever get it again. everyone will react differently."
