High risk ultrasound

Manjula

I'm five weeks two days and just had ultrasound as I've had previous miscarriages and am higher risk. The ovaries are clean, so not ectopic! They saw a gestational sac in the uterus that measured appropriate size for my weeks. They did not see a yolk sac or baby. Have others experienced this? I thought I would be able to see yolk sac. I'm going back in two weeks for repeat ultrasound.
