"i have had implanon since 08. this past october is my third one which will be 9years. i started out 105pds, which i stayed for 5 to 6 years i did gain weight after i stopped smoking. i am now 125pds. not complaining. i was getting acne but blame smoking. my period was really the main frustrations 1 month of spotting very light panty liner period.  to 3 months no periods. now i am  1 week  light periods 3 months no period. my only real concern here is that sometimes my periods are so light that  i only  know i&#039;m on is when it&#039;s found in my discharge often. no need for pads panty liner etc. wanted to know if anyone else was experiencing this."
