hCG level question

Katelyn

On Monday I had a blood draw done to test my hcg levels. I was at 12,000 (Monday I was 5 weeks and 6 days). I had to go back yesterday to do another to see how quickly the hcg hormone was producing. I went around the same time as Monday so it was as close to 48 hours as possible. The dr called me today and said it measured at 23,000...

So it didn't double in 48hrs. Do you think that everything will be okay? I'm not that far off! I just need some reassurance.
