Another ultrasound?

I'm undecided to get another ultrasound sooner I've had many losses and don't know if this is a viable pregnancy I'd like an ultrasound soon because I've been so full of fear that sometimes I begin to cry I just want to know already instead of think one moment yay maybe I'll have a baby or thinking of a way to bring myself up but then I think maybe I won't see a baby but there should be a growth right? I'm just an emotional wreck should I just ask for the ultrasound to be push up I just can't do this another week
