hot flashes

So I am pregnant with twins which is super exciting, but I am so very nervous bc I've recently had 2 miscarriages. Im currently 8w3d. Today I started having hot flashes which I read is a normal pregnancy symptom. But when I had my last mc, I got hot flashes the night before I mc'd. Anyone have experiences with hot flashes around this time? I'm just worrying myself sick. I know I shouldn't, but it's so hard not to. Thanks for your responses, ladies!!!
