Use to happen to me in my first and second trimester it from your hormones shooting up from what my Dr told me
Try laying down and drinking Gatorade or orange juice. They always help me!
It happen to me all the time during my 1&2 trimester I didn't even drive because I was so scared some.times It even felt like my heart rate increased so I just laid down and took a nap everytime it happen, just stay calm everything will be ok
First off, if you ever feel like that again do not drive! Its so dangerous, even just a block.... Second the feelings of being hot and nauseated is usually what people feel right before they pass out. Try having some Gatorade or something that has electrolytes in it. You need more than just water to stay hydrated. Also lay down and put your feet up for a bit.
Happened to me at work as well. You are probably dehydrated. Force the water down girl as much as you can.
Yeah its usually due to not having enough water or to eat. I passed out at work.
