Yes, I know a lot about this actually. The chemicals in the dark room, can cause, fetal deformities, miscarriage, low birth weight, etc. Its kinda like inhaling paint, it has the same effects that drugs do on fetuses. However, if you have good ventilation, like bring in a fan and aim it toward your face, and wear a mask, you and your baby should be fine! Just don’t go in there with no protection!
