"i got my implanon put in march 2010  because i didn&#039;t get on with the contraceptive pill. i read a lot of reviews before i had the implant and was terrified about weight gain side effects. i was always quite hormonal when i was due my period so that didn&#039;t bother me too much. since i have had my implant it has been brilliant, when i first got it my appetite did increase a lot and i did put on about 5kg but i exercised and ate sensibly and it soon came off again. i bleed about once every 3-4 months for around 10 days but it is light. the insertion of the implant didn&#039;t hurt. the area was just tender for a few days. i really recommend it as its so easy and you don&#039;t have to worry for 3years. just watch your appetite. that&#039;s my only advice."
