"when i first had nexaplanon inserted (oct. 2015) i was constantly bleeding although sometimes it would be so light i wouldn&#039;t need a panty liner. it stayed like that for about 6 months (march 2016) and since then i have not had a period at all and it is wonderful. also when i first got it in it would randomly make my arm numb and tingle. my gynecologist prescribed some medication to help nerves as the implant was pushing on some nerves. i have been on plenty different birth controls and this is by far my favourite. no periods, no cramps, no mood swings, no weight gain, and lastly no babies!"
