Hello, I'm so sorry for your loss.
I lost my first at 20 weeks and I know how devastating a late loss can be.
I hope you are bearing up.
The PM for my first baby found Ischemia, so probable cause was thought to be a clotting disorder. (But I went on to test negative for clotting, so the final opinion was that the loss was unexplained and 'just one of those things'
Because I then lost my second and third pregnancies to first trimester MC's I was then given a referral to the recurrent MC unit.
The recurrent MC unit are a lot more geared up for things like genetic issues than I found the regular consultant to be and to be honest their advice has been quite different.
They of of the opninon that genetic testing should have automatically been carried out after the first PM on the baby, (it was now too late to do this).
However they did immediately take blood from DH and me to genetic testing on us-Karotyping.
This test involves taking a bog standard small vial of blood and sending it off but the results do take a long time to come back- the consultant told us they take approx 8 weeks to come so they always give a 12 week appointment for the results to make sure they are back in time).
The test examines all our chromosomes for any known abnormalities.
Possibly your consultant thinks with healty DC born already it is unlikely to be a chromosomal issue but I would definitely want it excluded as an issue, if it were me, and certainly based on what the RMC think.
(For my first baby, the RMC consultant thinks it probably was a one-off genetic cause that allowed the baby to look completely healthy at PM but to give it a structural abnormality in the placenta that led to the Ischemia (the original hopsital where i delivered lost the placenta so this was not available at PM- In other words for their to be a genetic cause even though the baby looked otherwise perfect).
Sorry for the very long post, but I hope this answered your questions a little.
I'll probably report this post in a couple of days and ask MN to delete it as I don't want this much personal info sitting around forever, but wanted to try to help.
I wish you every blessing in TTC again (I'm also trying at the moment) and I hope we both get our BFP for 2013 babies.
