New carpet installation? Fumes? To do or not do?

C-Mouse

Soooo I purchased new carpeting for three bedrooms and a stair runner (Before getting pregnant). I’m still very early; 6 weeks today! I am supposed to have it all installed next week. I started reading online about fumes and toxic scary stuff... so of course now I’m freaking out and want to reschedule. It’s winter in Boston so the chance of leaving windows open is not possible (hello frozen pipes!). Has anyone installed carpets during their pregnancy? At what stage is best to do so? Thanks in advance!
