I'm 21 weeks and stupidly used white spirits before to get paint off something, I was only in contact with it for about 2 minutes while I put it on a sponge and wiped the paint off and I did it outside in the garden. I only really smelt it a tiny bit as I was outside so I was obviously well ventilated. I really just didn't think but as soon as I'd used it I washed my hands and anywhere that had contact with it (a little bit dripped on my leg but I washed it straight away).
Surely such little exposure won't be any harm? I've text my midwife to check, I've got myself into such a panic!
