Nervous and confused.

So got blood work done at 6w2ds hgc is at 66,542 but progesterone was low so they are putting me on supplements. They said they wanted me to come in for an ultrasound as soon as I could which freaks me out. Would they call me in if everything was ok.. I should have asked more questions but I got shell shocked and forgot everything I wanted to know. Has anyone felt with this. I've had miscarriage before so are they just checking fro make sure or are they worried somethings is wrong.
