Can it harm the baby?

Hi,

I found out I’m pregnant a week ago. I’m exactly 4 weeks. My husband and I are currently working on our house. We started doing the floors upstairs. We’re resanding and polishing. All the bedrooms and hallway. I came home and the house smells like paint I was so dizzy I had to leave. I opened all the windows before I left to air out the house. I came home and it’s slightly better then before. I made us a bed with sheets to sleep on downstairs on the floor in the living room while the floors dry upstairs. The ceiling fan downstairs and the window downstairs is open. All the windows upstairs are open. Is it safe to sleep here or can I harm the baby so early in my pregnancy ? It’s just for 2 or 3 nights. And during the day I’m never home. I’m super worried. Thank you
