Five mnths pregnant and can not feel my uterus below my belly button, my stomach isnt even hard yet! Could something be wrong?

Preg with sm uterus. Possibly. The best advice is to make an appt with an obstetrician, and to have a sonogram for fetal growth. This will provide the answer as to whether the baby is growing and appropriate for the age of your pregnancy.
How Far PG? I think the first question is how far in pregnancy are you? This should be fairly easy to determine if you are as far along as you believe. Ultrasound would be the best test and the measurements should help your physician determine just how many weeks pregnant you are and when your due is to be. Then you should have the answer to your question. Good luck and best wishes.
