I would consider a long talk with someone in ifectious diseases that is knowlegable in this specific area.... there are many things overseas that our people (male and female) are exposed to and many unknowns are brought home. it is not uncommon for those overseeas to be advised to avoid concieving for a period of time...depending on where they have been and what they are exposed to. i know in georgia there is a m.d. who specializes in travel med... this would be another avenue to persue for information..... i would doublt the bm is the problem.....
