At 9 weeks I only have a sac but no baby yet

Sonali
Hi guys, I am 9weeks pregnant and yesterday was my first on-gyn appointment. I was very excited and was expecting to see a tiny baby in my belly. At ultra sound the nurse said that I only have a sac and no baby inside and that it measures 5 weeks 5 days only. I am also bleeding and can see clots in my pad. They did some blood work and they said my hcg levels are 6200 but my progesterone is only 4.6 which they are expecting to atleast be 20. The doctor thinks I am going to miscarry the baby and in couple weeks if I don't then they would probably do the procedure 😞😞 is anyone else going through that?
