Welcome back! (sorry it has to be under these circumstances) I'm not sure if you remember me, my name is Christy, we spoke some while you and you wife were experiencing difficulties in the last pregnancy.
I'm glad they were able to give her a reason for the miscarriage. (I assume that is how they discovered that she has factor V) even thought I know that doesn't make things any easier.
Baby asprin and prenatals sound like a wonderful start.
How long has she been charting her bbt? Does she use fertility friend?
There are a few of us that have been charting for quite some time so if she (or you) have any questions, please feel free to ask us. I think she will find that it is a wonderful tool in ttc. She will be able to see when/if she is ovulating and that will raise your chances of having well timed sex.
If she has not tried them yet, I suggest that she use ovulation prediction tests (we refer to them as OPK's) They will be able to tell her 24-36 hours before ovulation and are great when paired with bbt charting.
Good luck and please keep us updated!
