Reason why dr did it is because for some weird reason i did a (5day) before period due test, 7days before my expected period and got a Positive. He wanted to know if i was more then 4 weeks prego. Seems like it is in normal 4 wk range. :)
I never had mine checked. are they worried and that is why they are checking yours? I was told that when it is checked, it's supposed to double every other day (or was it every day?). So, are getting it checked a second time? in searching, 3000 is within normal and looks good. good luck
