Beta came back at 488. I know single results don't mean anything on their own, but that seems like a good number for 17dpo so I'm a happy girl. Betabase says it's above median for a singleton and below median for twins, so no help there. :-)
Repeat beta isn't until 10/10. My clinic is so cruel.
Thanks for all of your kind comments over the past week. It's been an exciting one!!
