"i&#039;ve had nexplanon back in highschool, it was amazing. i lost weight, i didn&#039;t get my period and it was good to me. after the 3 years i switched to the pill and got pregnant, after i had my baby, i got back on the nexplanon and now its a totally different story. i gained about 10+ pounds in 8 months, haven&#039;t had a period til 8 months in and its been on going for over a week."
