Sounds like a pretty interesting number huh? In calling the doctor today, she said my "number" should be over 5000 to show how far along in my pregnancy I am. So, apparently there is a chart that coincides with the levels. The "number" is my HCG. Which means that I am between 3 and 5 weeks prego. I go in for an ultrasound next Thursday for a more exact timing. Yipee!!
