"i am 24 with no children. on november 21, 2014 i had my paragard removed and nexplanon inserted the same day. the insertion wasn&#039;t as bad as i thought it was going to be, and healed pretty quickly, about 1 week. i missed my first period and then they went back to normal, gradually getting shorter and lighter. my last period was 3 weeks long and now i am 1 week and 1 day late for my next. my symptoms didn&#039;t show up until recently: violent mood swings, headaches, nausea, dizziness, backache, acne on face &amp; body. i have gained 10lbs. even though my diet and exercise haven&#039;t changed at all. i like it ok enough, but there is a good chance i&#039;ll have it removed before 3 years."
