Sonogram

Here is a photo of the ultrasound at the moment of transfer. If you click through to Flickr and hover over that photo you'll see notes that kind of help explain things, but the black mass on the top and down the right side is my giant unhappy bladder, and the bulbous thing on the lower half is the uterus with the cervix off to the right. In the center of the uterus is a horizontal line: that's the catheter as it's transferring the embryos.
