"i just wanted to post another side to this i&#039;m 19 years old and i had the implanon in for two years. i had horrible mood swings, hot flashes, weight gain, etc. i didn&#039;t get a period, i loved that. there are other side effects though you&#039;re more likely to catch virus&#039; or have a sore throat all the time. headaches that are beyond crippling i went to the hospital for them. i had it removed not long ago to find out i may need help to have a child if i ever want one in the near future. i think everyone is different who receives it but really read over the side effects.
