No yolk sac: 5-6 weeks

Al

So my LmP was January 24th and I assume I’m 6 weeks and 1 day pregnant. However, when I went in for my first ultrasound today, they could only see the gestational sac and nothing else. No yolk or fetal pole. I am going back in a week. Please share positive stories of a successful pregnancy when your yolk sac wasn’t detected at around 6 weeks please! 😞
