Usually if the tied tubes grow back together and pregnancy occurs it happens in the first year or so after the procedure. The fact it has been five years makes me think it is not pregnancy, but exceptions do happen. I suspect you are experiencing normal hormonal fluctuation but if you miss your next period, do a home pregnancy test for your peace of mind.
