I will be 29 weeks pregnant on March 21st.  I did a fertility cycle and I am concerned.  I seem to be alot larger the second time around.  Everyone I meet asks if I am carrying twins.  Well....according to the ultrasound at 20 weeks...we saw only one.  I know every pregnancy and every woman is different but how large should my belly be at 29 weeks.  We measured it and at 28.1 weeks...it was 54 1/2 inches at the largest area.  Is this average or could there be more than one?  When we did the first ultra sound at 8 weeks...there were two babies and I lost one because it turned out to be an empty sac...what if...Is in the back of my mind.  Should I ask for another Ultrasound to see if more than one?  My doctor also says he only heard one heartbeat....???????????
