The beta was negative.
I'm actually feeling surprisingly OK about it. I think I pretty much processed my initial (admittedly crushing) grief over the weekend, so the news was not so much an additional blow, as a welcome bit of closure. This cycle is now officially over. Now I can move on and think about the future.
In the future, there will be another cycle. My doctor suggested March, I suggested February, and she said OK. So, there we are. I have one month to collect my thoughts, live a little, and have many nice glasses of wine. I'm planning to start today.
The other bad news is that nothing made it to freeze.
The silver lining is that my doctor emphasized that my response to stims was "great, considering...", and I interjected "my age?". She laughed and said, "yes". She also said that our embryo quality was "excellent". She says that sometimes she discourages couples from trying again, but that in our case, she really thinks we have a good chance of success if we are persistent.
Given that stubbornness is my most basic personality trait, I don't think that persistence is going to be a problem.
