After lots of waffling, I ended up calling the doctor's office first thing this morning and begging for another blood draw, just to reassure me that my hcg hadn't, like, leveled off or somehow gone back up or something. I knew this was a remote possibility at best, but I had to know. You can't go in for a procedure like that unless you're completely at rest in your mind, I think.
The doctor got the results rushed, and she called me this afternoon and said that my levels have slowed their descent a bit, but they're still going in the opposite direction that a healthy pregnancy would be. I said in a tiny voice, "But if they're slowing down, does that mean maybe...?" And she said, very kindly, that no, it just meant my hormones were taking their sweet time getting the message to my body to abort, and that if I let things go naturally she guessed it would be another two to four weeks before I'd lose the pregnancy on my own. She was very very kind. I just want to emphasize that. She kept saying things like, "You don't have to do anything at all yet if you're not ready."
But I think I am, now. I just want it done with, so that we can start moving on. My mind is finally coming to grips with the fact that, despite my sore breasts and my fatigue and my irritability, there is in fact no baby causing these symptoms. Just a cruel trick of nature, urging my uterus to cling to something that is no longer there.
So. I will see you on the other side, my friends. After I enjoy this rum and coke, which I've been craving for three solid weeks. (There's always a silver lining, I guess.) Thank you again for all your advise, which was very helpful. I had been planning not to get put out, just ask for a sedative, but after reading some of the comments I think I'm going with general anesthesia. I don't know if I want to be aware of the whole process, anyways, painful or not.
Well. Painful is such a relative term, isn't it?
