Sac only - 7w3d ultrasound

Mandi
Went in thinking I was 7w3d and only saw a sac. Doing my blood work to see if my levels are showing me to be earlier then we thought...
It's like I want to hold on hope that I'm just not far along... But it would have to be like two weeks difference and I just don't know if I can hold on to that hope.
