HCG levels, cramping, and ultrasound at 4 weeks

M

What were your hcg levels at 4 weeks? I’ve been having bad cramping so I went and was checked. She couldn’t see the pregnancy on the ultrasound, and my levels are 142.7. Going back to check my levels in 2 days, but is this normal?

The cramping just really worries me and then not even seeing anything on the screen scares me
