Am I miscarrying?

glyz 💕💕

I just want to ask.. at 6 weeks my 1st ultrasound heartbeat was 104. Last Saturday I was spotting. Not a lot, it just one wipe and that's it. Sunday we had an ultrasound, heartbeat was 37-82. What does it mean? Is there any hope? Pls help me. Thank you! I'm just really desperate.
