From the onset, they were classified as high risk due to being mo/di twins (monochorionic/diamniotic). It is now known that these pregnancies are much higher risk due to entanglement and other issues ("high risk" being a relative term). As it turns out, the doctors were right to assume this risk, as one of the twins has already received brain damage from (what they hypothesize) was inadequate blood flow. I'm generally against anything but procedures that are absolutely necessary, and the ultrasounds and MRI certainly were not voluntary on our part. Personally, from all the research I have gathered it seems like ultrasounds are quite safe, although I am not an expert. As for taking action, I had the same dilemma. Before we knew anything was wrong, one of the doctors ordered an MRI based on a hunch. I did not want to do the MRI unless it gave us some sort of information we could act on, and abortion was out of the question, legally and morally speaking under these circumstances. But we did it anyway, and at least the information has prepared us for what to expect.
