... stopped. I've just been having brown spotting here and there, which is normal. For the last two days I have had bright red spotting. I have had sharp pain in the area of the Nexplanon and when I checked it, it feels as if half is deeper in my arm then the other half. I can feel part of it but once I get the other end I have to push a little harder down to feel the rest. I have had Nexplanon before and it's never felt like this. Could there be a chance i may be pregnant if it's moved ? The first time I had it I gained a lot of weight and this time I have not. I asked my doctor about it and she says it's fine as long as you can still feel it but I'm not convinced it's doing its job.
