Miscarrying?

Tiffany

I went in for my first ultrasound today. Based on my last period I should be 10wks1day. The ultrasound showed a yolk sack and a very very small blob attached to it. So small the doctor isn’t even sure what it is. I have to go back in a week to see if there is any growth. Anybody have this and have a successful pregnancy? Doctor isn’t very hopeful but trying not to lose hope yet.
