"i got nexplanon inserted in september 2015 and loved it the first few months. my period lightened and it worked well as birth control (i haven&#039;t gotten pregnant). i noticed some weight gain and mood swings but i thought it was worth it for not getting pregnant. but in march 2016 i started having a constant, light period. i have now ended up having to have the nuvaring to help with the bleeding and i&#039;ll be getting the nexplanon taken out soon."
