triple Hugs to you. It is so confusing, isn't it?! Have you spoken to Dr S about the result yet and how they could impact his treatment plan?
I've had trisomy 2 and 18 in the two miscarriages that were tested. The good news is the bad news at the same time - there is nothing you can do about it. No treatment, no drugs etc. Even karyotyping might not be too conclusive for this (although if they are offering it, I'd do it - won't hurt), because it's very unlikely that they will find anything that causes this, they are spontaneous events. DH and I are both genetically fine, and it still happened.
I felt a bit deflated when we were told about the trisomy after the last mc - I had been gearing myself up for going down the NK cell testing route, but there is probably no point in doing that now, if I'm losing babies due to chromosomal abnormalities. I just wanted to do something.
On the other hand, there is a very good chance that it won't happen again. I realise that I am not the best example here, but I do believe my consultant who said that the possibility of it happening again is much lower for any future pregnancy, and that I have a good chance for it all to be OK next time.
My age is my issue here, and I can accept that this pushes the risk up. But the odds still give hope - for example, the risk for Downs in women over 40 is 1:60, which calculates to a 98% chance that everything will be fine. I can't remember how old you are triple, sorry, but I would say that chromosomal abnormalities, while un-treatable and therefore frustrating, are not that bad a diagnosis.
What has also helped me is to remind myself that my body has been doing the right thing by mc-ing non-viable pregnancies, so in a twisted way, this is reassuring.
So for now, DH and I are trying to do our bit by throwing lots of money taking supplements that are meant to help with egg and sperm quality. And hoping for the best...
I hope this helps - please feel free to pm me if you like!
