Thanks ladies. Its sadly comforting to know that there are at least a few other women who have been where I am. I just wish there were none of us.
Jo and Flowerchild - yep, having a child/children somehow is supposed to compensate for everything. If one more person tells me "just look at your beautiful son" or "at least you can get pregnant", I swear i am going to lose it!! Of course I am forever grateful for my precious boy. Doesn't mean I am any less sad about losing another child! And, yes, I do fall pg, albeit not "easily" but that doesn't get me anything when I just lose babies.

Michelle, BW and FC - I have a phone appt with Dr s next Thurs. I made the appt last week thanks to all your suggestions. Will see what he has to say but really still have to wait on results from these babies. If they were normal then I will certainly be pushing for pred. I am already using Clexane.
if results show another trisomy then will probably do PGD but I would still feel more comfortable adding in pred as well.
Just wish I could start trying again tomorrow. I know that is the only thing that will bring me "back", so to speak! Will probably be an agonisingly long wait, however. My HCG was 264,000 a few days prior to D&C and still feeling very sadly pg almost 2 weeks later. My HCG being that high then the suddeness of the loss is probably why I don't really expect genetic cause. It really seems to me that the babies were growing just as they should but were suddenly "killed". I don't know, I could be totally wrong. its just my "feeling'.
