No baby :-(

Annette
Went for first transvaginal US expecting to see baby and hear it's heart beat and instead dr told me there was a sac, placenta, but no baby. I thought I was 9wk 3d but he said I might not be as far long or it could be blighted ovum (mc). We have an appt next week and blood tests were drawn. 
I have all the symptoms- I even had to get larger bras and have a bump. It's heart wrenching to think that my body thinks it's pregnant but there might not even be a baby. Grieving.
