Sorry to go OT in this OT thread

but seeing the earlier post on mold wanted me to add my two cents. For those who have been following, my wife is pregnant and we got emergency AP a few weeks back so she could go to her brother's funeral. She'd been feeling sick/ not eating/drinking and we dismissed it as morning sickness coupled with being in a basement apartment with poor circulation. She hadn't been gaining any weight either.
Anyway, she stayed with her parents for a week and was able to eat and drink and put on six pounds. Within a few hours of her being back at home, she felt sick again and lost three pounds this past week. We're convinced it's mold. We told our landlord about this a few weeks ago and he said to keep the windows shut and a dehumidifier/fans on constantly. That's hard to do, considering my wife is in there all day.

Our lease expires at the end of October but we don't want to wait that long for her to be stuck in there. The plan is for her to go to Canada this weekend and stay until we find a place
and can move, hopefully in a week or two. This will be good for my wife's health and will help her mom, because she's had it rough since her brother's passing.
Any thoughts, considering my landlord doesn't claim anything is amiss in the apartment?
