I've been on implanon for 2 years 10 months ( almost expiring ) tomorrow will be 4 days late . I have no symptoms of my period or pms, besides peeing more and urge to drink water which I rarely do. I've been late before but I would blame it on my birth control, but that was when I had it for only a few months. I'm a little confused , can you get pregnant on the last few months of implanon ? Help!
