Well, have you been going for your prenatal checkups? Is this your first baby? It all depends on your body structure... with my first baby I did not show until I was about six months and never really looked fully ready to pop at all. I had strong abdominal muscles before I got pregnant and I guess those made me carry my baby very compactly. People would always ask me it he was growing. I assure you I gave birth to a very healthy baby. Ask your doctor if you have ANY concerns. I'm sure they have heard everything. Have you felt your baby move? Take good care of yourself and that baby from now on, no exceptions. As long as you are putting your child's needs first you can't go wrong.
