Hi!
If you and your wife were my patients, I would refer you for a consultation with a genetic counselor. From your story, it sounds as though there is definitely a strong concern for an inherited condition which may be causing the babies to be stillborn and premature. It will be necessary to find out your heritage (where you are from) and whether anyone in either family has medical problems and/or infertility. Once that information is determined, tests can be done to see if you and your wife are carriers of genetic traits which may be combining to cause your children to be stillborn.
The genetic counselor can then make recommendations about how likely it is that you will have a liveborn child.
Seeing a doctor would be a very good idea, since there is almost certainly an inherited problem.
Reading your post makes me sad too! I wish you the best of luck and a healthy baby!
