Living situation

I currently live with my dad and step mom because I am attending college. I am pregnant and can’t afford to live on my own atm. Their house is really old and has some complications, like the ceiling is caving in a little, there is mold in the bathroom and in the ceiling. They don’t have enough room for all of their things and everything is piled up almost to the ceiling and they have 8 dogs and a few cats that just gather hair, dirt everywhere and they always have flea and tick problems. I just moved in here over the summer and I was hoping we could get together and fix these problems but my step mom doesn’t want to pay for anything to be done. I always have the option of living with my mom, but that means I would have to quit college. I don’t know what to do.
