"I had my Nexplanon put in May of 2013 because I am horrible at taking the pill and did not have a good experience with the ring so I figured this might be the way to go. Now I don't know if it really was. Since being on this medication I have found that my anxiety level is much higher (which my anxiety is anger based) I go 2-3 weeks without a period then about 2-3 weeks ON with a period (usually light but still annoying) and the biggest kicker is my weight gain. I am coming up on a year being on this and have gained a total of about 18lbs without much change in my diet. It is very frustrating and it makes me want to have it removed.
