It's where you feel your body just heat up real fast. A lot of people experience this right before vomiting and that's probably the best thing I can compare it to. You don't have to be preggers to have it happen. I've gone through hot flashes when I was extremely sick. Trust me...If it's happened...You'll know it. :)

Yeah it's horrible!

I was only ever sick a few times in my first trimester and got a really hot flash and a really watery mought right before I threw up!

I unfortunately get hot flashes during af and night sweats. It really sucks!

I have been getting hot flashes as a side effect from clomid. It feels like i'm going to burst into flames!

I got hot flashes the first couple of weeks after going off the pill.
