So I just had my first appointment. Counting from my last period I should be 6 weeks 3 days. They did any ultrasound and only saw the yolk sac, but no baby. I'm scheduled for another Ultrasound in two weeks. The doctors were making me feel really nervous like they should've seen a baby and not just the yolk sac. Is the yolk sac a good sign? Because I am I just too early to see the baby yet? I'm praying that it's only because the weeks are off and I'm only more like 4 to 5 weeks pregnant as opposed to six. Has this ever happened to anyone?
