Most of the people I know that have been or are pregnant have started showing around 2-4 months. You NEED to get to a doctor. It's VERY VERY VERY important to have a checkup in the first trimester (the first three months). It's very important, especially if you think your stomach has gotten smaller. Good luck and if you need anything more, I'm always available to talk. Feel free to email me at anytime =].
