I'm about 16 wks pregnant with mono-di twins and my Dr just told me that even though everything is fine right now (the babies are exactly the same size and everything) and even though I am "the perfect person to be carrying twins" (because I have carried 3 large babies, don't go into early labor (all 3 were overdue) and have overly large healthy placentas right to the end) that I HAVE TO have a C-Section because of the risk of TTTS coming on during labor even if everything is fine up until then... they say it is hospital policy. I can't find anything that says the actual statistics of TTTS coming on during labor/delivery other than most people saying it is rare, they don't seem to have any info on HOW rare or HOW serious it is if it does happen... and I can't seem to find an easy way to find a new Dr. who will at least let me try to have them vaginally.... it would also be a VBAC situation because my last baby was breech (at 10 lb 2 oz) anyway, if anyone has info on statistics or info on a good Dr. in the greater Seattle area.... please help!
