I thought you said your doctor already told you that you were an early show-er but you haven't had an appointment to see her/him yet?
You don't need to get in any earlier unless something is wrong. Belly bloat isn't wrong. The reason women bloat is due to gassiness, more fluids, and to be really honest - a lot of people suck their stomachs in way more than they ever think they do. Pregnancy, even early pregnancy, is a time to let it all hang out.
