This is a really silly question but i just want to know how wierd i really am

As soon as it heats up and gets humid like it is today (i think its hot anyway) i think its 29deg i feel really sick like when i was pregnant and had morning sickness . I drink lots of water and have tried different salt replacments and stuff but i still feel really sick. Then i start to get headaches which at the end of the day if i dont take something turn into migranes

I am sick of it i feel really stupid going to the doc about it but may have to as i dont know how i will cope like that as i have another bub

Any ideas

TIA
