I don't understand my pregnancy I have ?

Larisse
Good afternoon, last night I went to the emergency room because I was bleeding a little bit. They did my blood test for my pregnancy hormones and it come back high. The decided to do a ultrasound they saw a sack but don't see a baby I'm 9 week and 5 days pregnant. After being in the emergency for 6 hrs they decided to do another blood test for my hormones to see if they dropped and they haven't its still high. I just don't understand how I don't have a baby in my sack if I'm getting symptoms I'm hungry, my breast are tender, my belly is growing too. I feel so scared I want to have a baby. Has anyone have had these problem or any advice please.
