"i got nexplanon during early august 2016. let&#039;s start with getting it in. the only painful part really was the needle (and that&#039;s a lot from me because i hate needles!) i usually get my period on the 22nd of each month and i guess my body continued to like that day because even on nexplanon i got my period the 22nd. this period was heavy. the heaviest i&#039;ve ever had. i had huge blood clots and it was so painful. it stopped after a week and now i&#039;m just lightly spotting. ive only had it for a month so i&#039;m going to hang in there. it&#039;s light like i could just wear panty liners, but constant blood is inconvenient. i haven&#039;t had horrid side effects yet. maybe increased anxiety? i already have anxiety disorder so tricky to tell"
