"i&#039;ve been on this for less than a month. i was recommended by my doctor and after considering the patch, chose nexplanon because of its convenience. i don&#039;t have to do anything at all. nothing to remember. in the first couple weeks, i noticed some mood swings, but that could have been because of the amount of stress i was under (college). i have had frequent brown discharge but i&#039;ve read that that&#039;s just my system regulating and clearing out the old blood. other than that, no problems. i&#039;m due to get my period tomorrow but am not having any of the normal symptoms, so i don&#039;t think it&#039;ll come."
