Are my HCG levels abnormal

Kendra

9/20 - 17 dpo - 327 miu/ml

9/22 - 19 dpo - 811 miu/ml

9/28 - 25 dpo - 9484 miu/ml

It seems to be more than doubling every two days so now I’m concerned about molar pregnancy or some other complication. My first ultrasound is on Monday 10/3 at exactly 6 weeks. Please somebody tell me this is normal.
