Miscarriage investigation success stories PLEASE

[Where there's hope]

Hello

I have just had an UNEXPLAINED miscarriage for the second time and am about to embark on the miscarriage investigation program which is related to Sydney IVF.

I have posted a similar question on the TTC thread, but would love to know if anyone here is pregnant/given birth after doing this or a similar program. In other words, did they find something, did it help and what did it involve?

Would be very grateful for any responses

WTH
