Thanks for the support and T&Ps ladies. I'm happy to report that they helped! My beta came back at 119, and as a result, my RE isn't concerned. She is pretty positive it's a SCH at this point. Today I'm back to brown spotting. The nurse initially said my RE would do an u/s to check for an SCH on Friday at beta #2, but changed her mind, and said she didn't feel like we need to do that after all.
So, for now, I'm obviously very happy and cautiously optimistic until we get through the next 2-3 weeks and some ultrasounds.
Thanks again for all the kind words!
