I saw a Sac!

And maybe the yolk sac! This is becoming really real for me now. The sac measured 5 weeks exactly. When I saw it, it just put the biggest smile on my face. It made working through a 12 hour day that much better. If just a sac can do that, image what an actual baby would do. I still feel pretty good. I'm starting to feel more tired and still really hungry all the time. I also scanned my sister today. Her baby measured 12w 5d ( I think its a little ahead, but not out of normal range). I've posted of picture of the sac, it is the small dark circle in the center of the picture.

WHAT IS BABY J UP TO?
At 5 weeks the baby is the size of a sesame seed its brain is the major organ developing.
