HCG concern...

My first draw was 9/17 and my level was 26. On 9/19, it shot up to 106.

Yesterday I had more blood drawn after having an unexpected ultrasound after some cramping. I was estimated to be 6w1d, but baby was measuring 5.5 weeks. The nurse just called to say my levels from yesterday were 27,000. The charts I’ve seen online all say that’s typically 6 week range. Am I overthinking and this is normal, or should I be concerned? I’m having another draw tomorrow to make sure things are rising, but I can’t help but be a little concerned after 2 prior losses. 😔
