Mold..

Hey ladies! I need some help ): my husband is military and we are soon going to be on the way to our next duty station... Japan .! (: I am so excited. But a month before we leave we are going to be staying with his parents for about 3 weeks. I LOVE my in laws. Only problem being they don't take care of their house... they smoke inside, and the house flooded and they never got it fixed so the place is infested with mold, up and downstairs.. I stayed there not pregnant and it killed my asthma as is and I was sick for two weeks when we left. And that was after me being there for 6 days. I read that mold can be a problem leading to miscarriage or other birth defects and I brought this up to my husband. He keeps telling me we will be okay and he will "fix it" idk how though because it's the WHOLE HOUSE. We have been living in a hotel the past two months because we are in transit in a different state for his training. We can't be staying in a hotel for another 3 weeks there and he has no other family we can stay with.. we need to be saving the money for the baby and his parents would be so upset.. I'm sorry about the rant but I have no idea what to do...
