Hi I've recently discovered I'm pregnant, I think I'm 6-7 weeks I'm planing on seeing a doctor within the next few weeks, but wasn't in a hurry as I've read they don't really do much until your 8 weeks. I'm currently working at an indoor pool, I work with chemicals like chlorine gas, hydro chloric acid, calcium chloride and other hazardous substances. We wear some PPE but a respirator is about the most protection we have, am I harming my baby?
