Question About Pregnancy...

[thesims3dude]

Hey everyone! I'm new here (just joined like 5 minutes ago) anyways, my question about the sims 3 is pregnancy,
I heard that they gradually get bigger? unlike the sims 2, where it's just 2 bumps? and also, how long are they pregnant for? I heard it was 6 days, but then I also heard that it was 3...? Did anyone go to fan-event and get to see a pregnant sim? Anyways, does anyone else have info about pregnancy? I don't know very much about it and that's what I'm looking forward to in the game, {blush} (among Create-A-Sim) heh  {clap}
