Call your doctor and ask it may just be that you hafta sit and watch what's going on around you
I was put on bed rest the day of my brother's graduation, and I still went. But I was put on bed rest because my fluids were low, so I stayed hydrated. I'd call your doctor if it was really serious.
Yes you should check with your doctor, the heat may not be so good for you bc I know it is so hot here in Alabama.
