Thanks for all of your support and warm welcomes. I went to my ultrasound today at 5w6d. There was a gestational sac, but no yolk sac. She did see a tiny dot that, and I quote, "something in the making." She seemed positive and said it was just too early.
Anyway, I'm really nervous because I thought there would be a yolk sac by 5w6d. Has anyone else experienced this?
