"i had implanon but in twice, so for six years, with no problems but crazy irregular periods. got my nexplanon implanted in aug 2015 and have had a period almost since with a weight gain of 25 pounds. have not enjoyed the nexplanon one bit other than i&#039;m not pregnant, but how could i be if i can&#039;t have sex cause i&#039;m always bleeding. currently i am sitting in the office waiting for them to remove here in about 5 minutes, can&#039;t wait!!"
