First Trimester internal furness

I honestly cannot remember being this hot with my first pregnancy. I'm currently 7w1 according to LMP and I'm dying of heat, and it doesnt help that its Spring (more like Summer) where in SA. Skin is on fire and starting to get extremely dizzy and nauseous from overheating.

I cant wear Summer Dresses to work as we have a uniform 🙈

I'm at that point where I might strip naked at work 😂

Does anyone have any tips? I'm drinking as much water as I can but still extremely thirsty.
