2nd Beta Numbers

I was more nervous today about my 2nd beta then I was about the 1st!
My fear of course was, that the level had dropped and not doubled like it was supposed to.
Nurse called around 12:45 to tell me I can start celebrating now, my 1st beta on Wed
came in at 274 and Today 2days later it came in at 688! So it more than doubled a little.
It is doubling at 1.50 days instead of every 2 days, so I think its safe to say I am definately
pregnant, I stiil cant get used to being able to say that word, while talking about myself!
Lat beta with RE is on Monday 3/3rd and then 1st ultrasound will be the following week.
