I've been on nexplanon for a little over a year. After about a month of having it implanted I had my period which lasted for about a year straight. I recently got off my period about a week ago which I am very happy about but I'm feeling really tired, a bit nauseous, my breasts have been tender for the past few days. I have a weird feeling that I could be pregnant but the chances of pregnancy on nexplanon are less than one percent. Do you think I could be pregnant?
