I had known for quite some time that dp's extended family (maternal side) had some kind of genetic thing that caused miscarriage..
I know that his grandma had it (8 kids, 8 miscarriages) and most of her daughters and sons have it (aunties and uncles) they were all given a blood test to find out.
But DP's mum wasn't tested (out of the family loop at the time) so none of Dp's immediate family have been either.
They've recently all been in contact again and as DP's sister (SIL) is looking to ttc soon she has been asking the questions.

So the thing they have is called "balanced translocation" from the info I can find it is when 2 bits of genetic stuff swap places, in a "balanced" way, in this case it is 6 and 11. It is harmless for the carrier, but can cause problems when ttc, as it can cause other genetic problems in the embryo which result in miscarriage.

Dp is reluctant to get tested. (he feels I would blame him for the miscarriages) I was all for it but after doing some more research, I dont really think it necessary either, even if he is a carrier there is nothing we can do about it unless we want to fork out heaps of $$ for PGD, which basically we just dont have.

but I am kinda in two minds about it, on one hand I'd like to know if I should expect to miscarry again and again....(already have two blighted ovums and countless "chemical" pregnancies that I don't even really acknowledge because its just too much to deal with)
I'd also like to know that its NOT because of some genetic thing and is just....what it is....IYKWIM?

Urghhh... so conflicted...

Anyone else have any knowledge of this issue?
