Numbers dont really mean a lot. As long as they double every 48-72 hours. Can you get your blood test done somewhere else? Your Doctor can send lab papers to a close by lab in the are you will be. I had this done once. I was in different state and my Doctor sent me to Quest diagnostics to get beta test done.
Try not to worry much. Good luck.
congratulations on the pregnancy, try not to stress, i know another lady had a beta of 32 to start with and now is like 30 weeks pregnant, my levels when i misscarried were 17 and then 72 never got any higher
