"i have been on bc since the 9th grade. i started to read forums and saw that being on  bc, for over 5 years could lead to abnormal paps. i decided to remove it to see if i lose the 30lbs i gained and with a change to an organic diet will reverse my precancerous  cells and if i&#039;ll lose weight too. i never had a period, no cramps, no headaches,  no mood swings. my only issue is the precancerous cells that are in a mild stage and haven&#039;t  reversed in almost two years. other than the weight gain i loved the nexplanon."
