Not symptom checking

Hi! Fairly new to the ttc world and I’m currently 5/6 dpo. I am a photographer in the south (so the heat is a B!) I had two very big shoots outdoors back to back. Today I’m feeling like shit, I’ve been experiencing a mild headache for 2-3 days and this morning I felt the headache more. I’m also tired beyond belief and extremely nauseous. My question is could over heating mess up my chances? I believe I overheated and my body is trying to get back to normal. I’ve been drinking water and Powerade. Should I try pedialite? I haven’t done anything strenuous just wanted to make sure I’m didn’t put myself out because of being exposed to heat for too long.
