Terrible work conditions

I am scheduled to work every Sunday. Me and two other coworkers have been complaining that on Sundays our air conditioner does not work. It has been up to 92 degrees in the office. Our boss comes back that it is not in our rental contract for the building to have air on the weekends. The entire office only works weekdays besides us three.

I don’t want to pull the pregnancy card but going into month 7, I feel lightheaded and nauseous sitting in this heat and trying to type paperwork!

Do you think it’s wrong to pull that preggo card?! We have been complaining about this issue since June

On top of that we’ve had an issue with giant roaches, and their response was that they already have a pest control person that comes out once a month and they won’t be increasing it. 🤦‍♀️ I’m ready for maternity leave. Sad part is, is that I work at a government agency.
