I am 35 weeks pregnant. Two nights ago my husband poured liquid plumber down the bathtub, and didn't think to open a window, turn on a fan, or even tell me. I was in the room across the hall when suddenly my throat started to burn, I started coughing and felt like I couldn't get a good breath, then the smell hit me and I hurried outside. I breathed the fresh air for a while before coming back in a turning on fans and opening windows. Two days later I am still coughing, and my voice is raspy. How could this have affected my baby?
