"i used to suffer from frequent migraine headaches associated with a spike in monthly estrogen levels, implanon helped me to have fewer headaches. the doctor who performed the implant didn&#039;t really numb up the area enough because there was pain associated with the little tube going in. it didn&#039;t last that long though, but left a pretty nasty dark red bruise for about a week and was tender for about a month. internally i feel great. there are no mood swings and menstrual cramps last about a day. my sex drive is normal. the only thing that i don&#039;t like is that i almost always have the dark &quot;end of your period&quot; discharge. for three weeks out of the month i have this brown sludge, but it&#039;s worth it because i won&#039;t get pregnant for three years!"
