New Home Fumes-Pregnancy

My husband and I bought a new build home and got the keys today! Super exciting! But now my husband is freaking out because of the fumes from all the new products in the home. (Paint, carpet, flooring, drywall, the fumes from the burning oil in our new heater...etc) He won’t even let me walk into the new house for the next week before we actually move our things into it, and he’s still freaking out about after we move in too. I get he is worried about me and the baby, and I know it isn’t great to be around fresh paint fumes and all those freshly applied chemicals in the home. But what else are we supposed to do? Lol we move in next weekend.

Has anyone ever dealt with this issue? Is there a way to get rid of the fumes fast? We’re already leaving windows open and the heat/ac on. Is there anything else? Is it really that toxic to move into a brand new home? Or is my husband just a little too worried?
