Wildfire smoke

So our city is filled with wildfire smoke today, the risk index was at a 10+ which is the highest it can be. I’m 33 weeks pregnant and worried this is going to have a negative impact on my baby. Does anyone know of the risk factors? Unfortunately I had to work today so I had to and will have to go outside to get home, the place I work at is also filled with smoke even tho it’s indoors. My eyes nose and throat have been burning all morning.
