I found a spot on my bed, I thought it might be mold and smelled it, didn't smell like anything could I get sick if it was mold?

Don't worry. We inhale mold spores every day. Our reactions vary. But this item you mention is not worthy of any concern. If you find you spend a lot of time worrying about things that might go wrong with your health, it's worth talking to a counselor so you can redirect your focus onto more fruitful adventures.
