So, at my scan last week, I asked the tech if there was another sac because of the dark, river shaped image in the upper left corner of the scan; close to the sac. She said "oh, no; there is only one". But, she never explained what that spot was. I googled and any fluid on an image would appear black; so that clearly has to be blood or fluid of some sort. Anyone know what it might be?
I'll be sure to ask at my next scan on Friday, but I'm curious in the mean time. The image would disappear and then reappear depending on the angle of the u/s doppler. So, I'm not sure if I called the doctor now if they would have a copy of the image with the spot.
