well i have blue cross and when i called and told my dr i was pregnant they had me go in for an u/s to see if it was tubal also cause i had an eptopic before and then after that the dr said i needed to have blood work done again so they could check to see how far along i am and then i had a second u/s to get my due date and i think i will have another u/s at around 16-20 weeks because they need to do that to check the baby's heart and other vitals and make sure everything is good so i wouldnt worry to much about not having another u/s because they can always work around the insurance company if they really think you need to have the u/s!! good luck and i hope you see your baby soon!! i havent seen mine since i was 6 weeks along and it is killing me to see my baby again!! but i did get to hear the heartbeat yesterday with the doppler so that was wonderful!!
