"i had previously been on the shot for 9 months before. i didn&#039;t experience any of the horrible side effects of the shot until after my 3rd shot. i had gained 16 lbs. nonetheless, i decided it was time for a change. 
so far my experience has been pleasant. the insertion did not hurt except the numbing. i did not bruise. and it&#039;s been long healed. i did have some small pimples pop up, skin irritation that went away in a week. i hadn&#039;t had my period since october 2012, shortly after getting the depo shot. in july 2013, a month after getting nexplanon, i began spotting. it lasted about 7-8 days. but have not had any spotting/periods since then. i have lost 4lbs."
