I'm 31 weeks and 4 days. Im feeling light headed with a mild headace. I also feel as if I'm about to pass out. I tried walking around and ive tried sitting and laying down. Im also getting over heated at times. What should i do? Should i try other methods or call my doctor. The doctor and hospital is 45min away from. I dont want to waste calling someone for a ride and nothing dangerously wrong.
