"i had my nexplanon inserted may 29, 2013 i was on the pill and it was my pill free week. so my cycle was supposed to start soon. as i had nexplanon inserted my cycle started. it lasted for 10 days, moderate flow, flow for 4 days then light the last 6. i didn&#039;t feel anything but a little burning from the numbing shot. my arm now has a scar but when i first got it the bruising was kind of bad but it still gets better with the days. i love nexplanon."
