I think I messed up I’m freaking out

Okay so first time being pregnant and I’m 5 weeks and 3 days ish... I work in an office that is freezing and I put my small heater on my desk and had it blowing on my face. It wasn’t crazy hot but warm, I swear the pregnancy brain is real I totally realized half way through OMG I can’t be doing anything heat wise what the heck... now I’m freaking out I turned it off immediately cause I actually got a little dizzy and light headed.

Do you think I could have hurt this pregnancy? It was like 20 mins not like a hot tub or anything but ugh I am freaking out.
