"i had a heavy period that lasted a good 3 weeks, beginning 2 days after insertion. irregular periods for a while (boo), zero cramps (yay!). after a few months, i have light spotting for maybe 3/4 days per month &amp; it is painless. gained about 10lbs but not really an issue for me. i had manageable depression before getting nexplanon(etonogestrel). now i have severe mood swings, depressed mood on a regular basis, had my 1st panic attack over something silly, also having impulse control issues. seeing a psychologist now. they think i should wait it out but i am done living like this. i really do think nexplanon made my depression &amp; anxiety so much worse. getting it removed this week. be sure to discuss history of depression before getting this!"
