Deflated yolk sac at 9 weeks

Ashley

I went in for my first ultrasound yesterday and the woman said everything looked good; baby was kicking, great cord, good heartbeat 167, measuring right on schedule, but she said the yolk sac was deflated. She made it sound like it was ok, but now I’m kicking myself for not asking more questions.. does anyone know if it’s ok that the yolk sak is deflating at 9 weeks + 1 day??
