"the numbing shot hurt but i couldn&#039;t feel the insertion of nexplanon. the days following, i had a bruise which lasted for a week or two. about a week and a half after getting the implant, i started spotting and didn&#039;t stop for two and a half months, which was pretty discouraging at first, however it was very light and i knew my body could take time to adjust to the new hormone so i waited it out. side note: i highly suggest u by kotex panty liners, they don&#039;t feel like they&#039;re even there (not sponsored, wish i was ;) ) when i stopped spotting, no period for around 50 days. since then, my cycle has been around 40-45 days and light period. which is pretty nice cause it&#039;s less periods per year than the average 28-30 day cycle i&#039;ve always had."
