my first BETA my numbers were around 275 and then three days later they had jumped to close to 600. Not sure if mine were above or normal, but I'm 29wk4d w/ twins :)
I had my first beta at around 4 weeks 5 days & they came back at 1000. Tested a week later & they are now 18,439. I am going back for a repeat u/s on Wednesday to check for multiples. Not sure what to think right now!
