I got my Nexplanon put in about 2 1/2 years ago, I bled a little at the start and then nothing for about one year. The next year I would have bled quarterly... Now I bleed for about 5 days straight every other week, experience beast tenderness and have frequently mood swings. Are these side effects happening as I am due a new one in December (now June) or should I be concerned?

Amy help is appreciated... xx
