Why do people think it is appropriate to say, "Are you sure it is not twins?"!!! Yes, I know my belly is big and I still have 6 more weeks. The doctor says that on your second pregnancy the baby doesn't sit in your pelvis like your first did so it tends to make your belly bigger. She probably is trying to make me feel better. This pregnancy has been fairly easy but I am definitely feeling like I am getting close. I don't have the energy that I once did and am having some aches and pains but I can't complain.
