I am 4 weeks pregnant. We are currently decorating upstairs and my partner was sanding the walls using an electric sander, he closed the doors and taped it all up to minimise the dust around the house, and he had a mask on and the window open. I stayed downstairs in the kitchen to keep away from the dust as I didn’t have a mask. Unbeknown to me, the crazy wind we’ve had this weekend was blowing the sanding dust down through the floorboards into the soil pipe tube which runs down a corner in our kitchen, which filled the kitchen with sanding dust. It was so fine I didn’t even notice it, I was in there for nearly 2 hours breathing it in without knowing. When I looked around I noticed a fairly thick layer of dust on the worktops and floor and of course I’ve googled it, and everywhere is saying it’s really bad to be exposed to paint dust especially in the first trimester because the chemicals in the paint can cause birth defects 😢 I’m so worried we’ve done permanent damage to my potential rainbow baby 😩 I’ve called 111 and I have to go and have a blood test tomorrow to check for lead poisoning as my house was built in the 70s, unlikely to have lead paint on the interior walls but testing as a precaution. Regardless of the lead issue, has anyone else ever been exposed to sanding/paint dust during early pregnancy and the baby has been fine? Going out of my mind as I’ve already lost a baby to birth defects. Thank you.
