"i had my implanon inserted 4 weeks ago. i had my period for 5 days after insertion but it was the same length of time and flow as my period on the pill. after that i haven&#039;t had any breakthrough bleeding yet. i have noticed, however, weight fluctuation of about 5 pounds but nothing crazy. i was nauseous for the first week, and now am noticing a bit of emotional liability (i cry at the drop of a hat, i can&#039;t watch tv without crying). but so far it doesn&#039;t bother me. i&#039;ll probably put in another review if anything changes. as for now, so far so good!
