I am currently 38 weeks pregnant and living with my husband and our dog at my parents house. The house is split into two sections so we have our own bedroom and bathroom area and our own lounge area, we share a kitchen and utility room which works fine. My parents have a log fire in their lounge which they light every night, sometimes it can get quite smoky so I open our bedroom windows and air our upstairs area out, it really worries me with the association of fire smoke and autism with pregnancy!?
