I am 4 months pregnant. My husband had gone to the trouble to picking a low-odour zero-VOC Paint, but then decided to use paint thinner to clean the brushes. He did all of this outside on the front proch and left the paint thinner on the front porch, but the door was open and fumes wafted into the house. He promptly took the paint thinner away to the garage and aired out the house. My exposure was less than a few minutes. Any danger?
