and then there was one

I really thought I had hit some kind of new low point. But, incredibly, things have gone from bad to worse.
The ultrasound this morning shows only 1 decent size follicle. The other one appears to not be growing. There are also a couple under 1cm, but they too look like they're just hanging around and not going anywhere.
And it looks like my left tube is blocked (despite 2 previous HSGs that had showed it to be open).

So...the million dollar question.
Should I stay or should I go?

If I go there will be trouble: this is my last try with my own eggs. I think it's pretty clear that my ovary is not up to the job. Goodbye to my whitechololatebabydream.

If I stay there it will be double: what are the chances that this 1 egg will produce 1 good embryo? And if it does what the chances it could actually implant, given the appearance of the toxic tube? Is it worth another week in NY? Is it worth going through the retrieval, the anxious hours of waiting to see if the egg has fertilized, the embryo is developing..and then 2 weeks of projesterone injections?

I think I have till tomorrow to decide.

What think?
