6 weeks pregnant and I feel like a big giant elephant?

I just found out that I was pregnant 2 weeks ago and ever since then I feel like a blimp. I am excited about the baby so much but I feel so ugly. will this feeling go away, I don't even want to leave the house, I have been wearing my husbands sweat shirts that is the only way I feel comfortable. I am eating 3 meals a day which I never did before and I have never been a snacker. Could the bloating be from me not smoking anymore olus the 3 meals a day? I guess I wnat to know if it is normal to feel bloated this early in the pregnancy.
