Thank you all so much for your responses. Here's what's happening:
She said she has had increased discharge, but just thought it was because she had twins. Never really noticed a gush or trickle.
She is to see both the perinatologist and her OB on Mon for ultrasound. They will check the fluid again and determine if it was a gross rupture. The feeling is that it most likely will not reseal, but they will check and make sure.
I spoke with our Clinical Nurse Specialist yesterday to get her thoughts. She said that it is dicey either way (no kidding.) She also gave me some info that I was not aware of: the literature has shown that often in early ruptures like this, there is usually some kind of infection already present. Also worth noting is that this mom has TMJ and had to have a cracked wisdom tooth cut out two or three weeks ago. If I am not mistaken, there has been a link found between dental work/problems and PTL (not sure about PROM, though.) She also developed a temp last week and had what she thought was the same stomach bug her two year old had. Another thing our CNS said was that babies that suffer from infections in utero have shown an increased incidence of CP.
I spent a couple hours with the mom last night. She said that she has good and bad moments, and has been looking online for case studies and any kind of info she can find. She said that she and her husband had basically made the decision before they left the perinatologist's office. She said that she could not handle losing both, and did not want her body to take over via mother nature and lose the whole pregnancy. Although there is no guarantee for A, she said she was not willing to lose both because they chose to gamble.
My heart just hurts for her
. She found support groups in her research online yesterday. She found a couple instances where there was a loss in the second trimester, and apparently at that stage, the fetus will "fossilize" or "mummify." She is pretty freaked out over carrying and delivering B in this form whenever A delivers. I am afraid too, because I promised her I would be her nurse ten weeks ago when she found out she was pregnant, and I am just worried that I won't be able to handle it. I would not dream of backing out on her - I think that is when she will need me the most.
I thank you all again for your thoughts and prayers. I'll keep you updated.
