I agree it's probably bloated. Make sure you drink your water so that you don't retain any extra. I'm only almost 5 weeks but this is my 3rd. I'm scared to pop out too early :)
So you are 8wks 3days pregnant, or thereabout? It is more than likely bloatedness. This pregnancy, which is my 2nd, I felt bloated and full...from about 8 weeks on. I didn't start showing til around my 18th week. Good luck!
I too noticed w/my subsequent pregnancies that I showed sooner too. I think it's perfectly normal although you are really early. Have you gained much weight?
