i just had a weird type of funny turn, i was lying down in bed and became hot and lightheaded and shaky and thought i was going to faint, it lasted about 10 minutes and i when i recovered enough i reached for my BP monitor and the reading was 75/39 my usual blood pressure is approx 100/60. Is this anything to worry about? I just thought it was weird as i was lying down at time, how can you almost faint when lying down? could it be all hormones, i am pg.
