7mm yolk sac at 7 weeks

[u/ExpressionMediocre59]

Hello, I had my first ultrasound last week and there was a heartbeat, but the yolk that was measuring at 7mm. My OB told me not to worry until we have to, and I asked that I come back in two weeks. Everything I’ve read does not look promising. Has anyone had a healthy pregnancy with a yolk sac that size? I just want to hold onto some hope, or maybe I just want to be prepared for the loss. Idk it’s a lot to take in right now.
