"i had the nexplanon implant put in, in september of 2014, the incertion was painless because they numbed the area first. i had a ton of bruising at the site and the pain and bruising lasted a while. i had one period the week after i got the nexplanon but it was light and lasted maybe 5 days.. then no period at all. i started noticing weight gain, about 15 pounds and for my height it showed a lot. i was nauseous everyday, very moody, and stressed out for no reason. i got it out 2 days ago and i already feel better. not nauseous at all, and i was nauseous for 9 months everyday. i wouldn&#039;t recommend this just because of how it made me feel, but it may work for other people. on the bright side i had no period.."
