If you have mold in your home it is a serious matter that needs to be dealt with. The longer you wait, the more it will spread. If it gets into your hvac system, it could end up all over the house. All molds can make you very sick,

When mold was found in my attic we had to move out of the house for a week while a remediation company did the cleanup. The mold was making my daughter sick, and we were concerned that if any additional mold spores were in the air during the cleanup, it could have made her even worse.
Do yourself a big favor and find a couple of local remediation companies and have them come to your home to give a free evaluation. You probably will be surprised at what they have to say.
