Is there any correlation?

Is there a correlation with hcg levels and heartbeats detectable on an ultrasound?

My wife is going in for her first apt on Thursday and she has been googling a million and one things because she hasn’t been getting any pregnancy symptoms except frequent urination and it came up that if your hcg isn’t over 25000 you won’t see the heart beat.. last draw was Friday and she was 8521 so she’s freaking out.

Has anyone experience this?
