Gestational Sac but no embryo/fetus

Katie • I`m awesome!

I'm supposed to be around 7 weeks preg2. Had my dating scan today. They could see a gestational sac measuring 8w3d and a yolk sac. Internal ultrasound didn't help much. Saw what might be a CRL of 5w6d but I have to go back in 2 weeks. I'm freaking out. Has anyone else had this? Was it good or bad news?
