Paint fumes and hair dye concerns

I have been very cautious my entire pregnancy about what I put on and into my body as well as the toxins and chemicals I am exposed to. At 31 weeks pregnant yesterday we got a few rooms in our house painted and tomorrow I have an appointment to get my hair done. I feel like the paint fumes and hair dye is too much at once and it’s giving me anxiety 😔 am I worrying for nothing? I’ve been airing out the house as much as possible and hopefully won’t be too long at the hair dresser tomorrow. I’m just so scared to cause harm to my baby
