I will also add that I had windows open, ceiling fan going plus two other box fans. And we used paint from home depot (behr).
My husband and I found out we were expecting the day we closed on our first home in June. I called my doctor for this very reason because there was a lot of painting to be done. My doctor advised me it's ok to paint in a well ventilated room, latex free paint as well. You can ask any person who deals with paint these two questions...is it latex free and is it safe for pregnant women to use...
And its in rooms with windows I can open with a fan and wearing a mask
