"when i got nexplanon i bled for 6 months straight, however, my period was light and manageable (i was very active in sports). my doctor prescribed an oral birth control to help regulate my flow and i took it for three weeks. i didn&#039;t get my period for the next 18ish months. the last year of my bc came with very irregular spotting and occasional periods. with nexplanon, i noticed my mood was pretty sensitive when i was bleeding. i did not experience any weight gain. overall, i have loved this birth control. my husband and i have used this as our sole method of protection and are confident with it."
