Month of nauseous

Kat

I been nauseous for nearly a month now every day. a week or two ago I had some spotting for 3 days. Smells are stronger and I am more tired and grouchy. I am on the nexplanon for almost three years. March 30th will make a full 3 years with it. I have took 3 pregnancy test to make sure that wasn't the case, also I just started my period. Has anyone else felt like this close to the end of the three years with the nexplanon?
