Being overly cautious?

Just found out this week I’m pregnant- 2 weeks ago I was staining 2 pieces of furniture outside then today I brought them in thinking they aired out enough well after about 30 mins I could smell the odor. Brought a fan down and opened a couple windows to hopefully let the smell out and didn’t help. So back out to the garage they went.

I felt a little light headed from the fumes should I be worried?? Between staining and now smelling inside today I’m nervous about the fumes while pregnant. Thank you!
