The heat!!!

Mallory • I`m 27 and expecting my first after 7 months of TTC with endometriosis, PCOS and hypothyroidism.
UPDATE: I have the sweetest dad in the world. He left work and showed up at my house with a brand new window AC unit and installed it. 
So our AC died yesterday...well it's dying a slow and terrible death on a unit that's less than 2 years old....so they'll be fixing it for free...meaning they're taking their sweet time getting here. What I'm wondering is can sitting in the heat in the house be a dangerous thing for my pregnancy?  It's supposed to be well over 100 today so I'm anticipating our house will be about 85-90 inside (since the unit is still sort of working). When I called I tried to play the pregnancy card and they said "I'll put you in for first thing tomorrow morning between 10 and 2" 😡
Should I just abandon ship and go stay at my dad's house?
