Someone ease my mind

Jade • Pregnant with #3 🩷💙

I had a doctors app today, in 6w4d, I got my first blood test when I would’ve been 4w3d and my hcg levels came back as 740 but my doctor told me that they were low. So curious me looked up average levels and that’s within range for 4 weeks? Could anyone tell me what their levels were?
