"i had my nexplanon inserted in jan of this year. 2016. it&#039;s now june and luckily i get it out 1 week from today and am getting my tubes tied and endometrial ablation(so i don&#039;t have period) due to the side effects of this. like others stated it is effective in not getting you pregnant but i too am like a lot of others who have a period constantly with maybe 1-2 days off after about 2 straight weeks then back on. it&#039;s inconsistent and i&#039;m always on. that&#039;s not the only horrible part... second, it&#039;s super heavy. like gushing within 30 min of a changing tampon. i have to wear super tampons (which hurt) and a pad and i still end up changing underwear all day! my husband is just as frustrated as i am. i&#039;m moody. migraines. backaches. horrible!"
