We went in for our 7wk ultrasound today, but little baby Garton#2 was too small to see. The doc said he could clearly see the yoke sac and everything is in the right place, but the baby is under 1/4cm, which means it won't show up on the ultrasound. We scheduled another ultrasound for Friday the 27th. He said my due date may be closer to April 6 instead of April 3rd. He thinks I may have conceived at the end of my fertile period.
