"i first got nexplanon may 2014 and my arm was pretty bruised after, as expected, but i had no pain otherwise. i had no periods (except for light spotting twice, both lasting less than 24 hours). i had no weight gain and no mood swings, but the first few weeks i felt so tired! i was very apathetic and exhausted for no reason - i never adjusted my eating or sleeping habits so i had nothing other to attribute it to than the implant. so july 2015 (14 month in) i had my first full blown period. then a week later i had another and then a week after that i started spotting. it&#039;s now sept 15 and my marathon period is still happening. i saw my gyno and i&#039;ve been taking estadiol daily which is only slightly helping. gonna give it thru the month :/"
