Drywall dust

My work is renovating and my office is right next to the construction and my office is covered in drywall dust! I have temporarily moved myself into a coworkers office that works a different shift than me but all of my stuff is covered and the smell is making me so sick. I keep getting a pounding headache, naseous, and my heart rate keeps increasing when I need to get something from my office. I'm getting really nervous about how this is affecting me and my baby. I'm only 7 weeks pregnant and am not ready to tell work and don't know how to go about getting my office situation resolved... Any advice or anyone know how inhaling drywall dust will affect me or my baby?
