"i had nexplanon inserted oct 26th 2016. i haven&#039;t had a period since december, which will always worry me. plus side i haven&#039;t had any reasonable weight gain from insert. downsides are the depression, mood swings, and my acne (i haven&#039;t had since high school) came back. i haven&#039;t lost sex drive. but i have pregnancy symptoms (per usual for most bc&#039;s). the biggest concern for me is getting no periods at all. eventually if mood swing/depression worsens i will probably have insert removed with my gc."
