"i have had implanon inserted since november 2010 after the birth of my son. no period until yesterday, which surprised me (after 19 months without periods). i have had no weight gain (despite a very good appetite and a love for cooking), but no libido at all (because of the breastfeeding as well). i stopped breastfeeding 2 months ago when my son was 18 month old, maybe my hormones production changed, and the birth control in the same time. i do acrobatic dance too and i wonder if the implant is still in place: for some of my tricks my partner needs to grab my arm over the implant.  i will check with the doctor on monday. i may ask her to remove it and take regular pills instead."
