"i had got my implant birth control put in oct. 2016. i was the lucky one to hit all the side affects. mood swings, banging headaches and  hot/cold flashes. oh and of course i&#039;m that 1 in a million girl who has had her period for 6-7 months now. i&#039;m around 140 lbs now. i&#039;ve gained a little weight but i&#039;m not sure if that was from the birth control, or me over eating sometimes. i&#039;ve had the birth control for about 7/8 months now. i still get the mild headaches everyday, motrin helps with that. my sex-drive decreased tremendously. doc said to try taking 600 mg ibu-profen every 6hrs for 5 days straight to reduce the flow of my period. i&#039;ve tried it but i wasn&#039;t very consistent due to busy work schedule. so far, i&#039;m thinking about removing the nexplanon."
