I’ve had the implant for years and just had a new one put in January of 2018. I had a different doctor reinsert the new one. I does seem bigger than the old one but that could be because it was 4 years ago. I had no periods all 4 years. today June of 2018 I started my first period in almost 5 years and am a little worried. Will these stop? Why am I having one after so long?
