sort of. as above poster said, it's the bloating that makes you look farther along than you are.
i was in maternity at 6 weeks pregnant.
so your baby isn't any larger, but all the bloating and larger ovaries make you look bigger than you are.
if it was a stimulated cycle of ivf .. there is a certain amount of bloating that comes from that .. and if a pregnancy happens, the ovaries take around 10 weeks sometimes to go down (that was how long mine took earlier in the year) so this can make you look pregnant before you would normally be showing .. hard to keep it a secret in 1st trimester when you are showing already!!!
