"i first had nexplanon implanted in april 2015 because of my heavy and painful cramping. i was told that it would be normal for the first 2 or 3 months to spot or bleed, as it was my body becoming used to it. i stuck it out for the first few months and then asked my doctor why i kept bleeding. she told me for some people it may take up to 6 months. i stuck it out until that 6th month and figured that it might just take a little longer than most people. however, i never stopped bleeding. i always had to wear panty liners or light pads. it was never just spotting either; sometimes the bleeding would get so bad it would be like a period. after a year, i got it taken out in may 2016. it&#039;s been over a year since and my cycle varies drastically."
