Thanks for the query.
Once check for the positivity of antiphospolipid antibodies
in your wife.
If that comes positive she has to take steroid treatment for few months.
Then your wife can go for ovulation induction
with your doctor's advice and you plan intercourse around the time of ovulation.
After conceiving let her continue the pregnancy
with the support of progesterone
and aspirin etc.
By these the possibility of future fetal loss can be prevented to some extent.
