Brown Spotting - no tmi pic

Danielle • Growing baby no. 1 currently 5 weeks!
I've had brown spotting this morning (I'm 10 weeks) and I called nurses on call who told me to rush to emergency so I did. Had cramping and feeling dizzy Doc didn't seem too concerned, offered me a speculum to which I declined and told me to go get an untrasound but no one can fit me in today. I just want to know if my baby is okay??!
Has anyone had this should I be worried :(
