The nurse said on the phone that "once you have 3 betas doubling every 48 hours you move on to the US - no more betas". Which I wish was not the case. I would prefer to do another to see the number near the time of the ultrasound so I can be mentally prepared. Low beta (which mine are still low) are more often associated with poor outcome or worse, like an ectopic.
Now that I write this I think I am going to call and see if I can get orders for a beta later this week. Can you tell I am still freaking out?
