So. Now we wait.
All went well today - and thanks so much for your good wishes. I checked my phone shortly before we went into the transfer room, and it was delightful to know people were thinking of us.
Totsicle survived, and the transfer went without a hitch: three times now, and I think I have finally perfected the art of full-enough-bladder-without-hideous-discomfort.
Beta is next Saturday the 22nd, though we have told our families it's the 24th, to give us either a.) a few days to deal with disappointment, or b.) time to get through the second test. Once bitten, twice shy.
I am under no illusions whatsoever that I will be able to resist the pee stick. Drugstore. Tomorrow. Then, the wait really begins.
