Anyone been in the same situation. Scans

Leanne • 24 years old from North Wales. I have a 20 month old daughter and I am engaged to my hazzy

Early scan reveled nothing but a thick womb lining and a buldge uterus. They said the buldged uterus may or may not house a successful pregnancy.

Had bloods taken today as well and they were over 700 so will be back on Wednesday for another lot to see if they go up. Hopfully back for a re scan soon after and there will be at least a sac and yolk but now I am scared that it's not going to happen.

Has anyone been in the same situation?
