"i had my implanon inserted when i discovered i could no longer take estrogen birth control. the progesterone only pills caused me to bleed a lot, mainly due to the fact i had to take the pill at the exact same time every day, it was impossible for me. so that left me with an iud or implanon. it took nearly a month for the sensitivity to go away after the implant but since then i have had no issues. only side effect i have noticed is spotting, normally just a little but it&#039;s constant. no regular heavy periods, no cramping, no hormone mood swings or weight gain. i think it&#039;s the best fit for me!"
