I've just started wearing matenity pants and I'm coming up to 11 weeks. I don't think its a baby bump as such, its more just a tummy... possibly from bloating/normal weight gain. I know where my uterus currently is (thanks to What to Expect) and its not where I am "showing".

But whatever, the maternity clothes are so much more comfortable than my tailored suits that were getting far too tight for me!
