Working and morning sickness

K

So i work in the medical field so i have to wear a mask all day at work. But this morning i had my first morning sickness at work and felt pretty awful. I started feeling alittle better but everytime i put my mask back on i was instantly nausea and felt over heated. Any advice to help with this? I left work today and gonna rest up but i have to work tomorrow and i cant be missing work for this.
