Had my 3rd put in back in Feb. Was fine for a week or so then had spotting for a few weeks. GP gave me Norethistharone so stop the bleeding which it did. Until 3 weeks ago, the spotting started again, barely anything but needing a thin liner most days. Then the last 2 days bleeding has got heavier, some clots etc.... Is this fairly common for the implant? GP didn't seem concerned last time and the previous 2 implants I've had were implanon and I had no bleeding but this one is nexplanon so wondering if this usually happens?
