18 weeks and 2 days and dizzy and lightheaded

Haley

I just randomly got extremely dizzy and lightheaded. Everything started to sound weird and I think I almost passed out. I also got nauseous. This week I’ve been randomly dizzy but nothing like this.. does anyone know what it could be? I kinda started getting crampy too but that’s really normal and has been happening my entire pregnancy. I would call my doctor but they aren’t open today.

When it happened I had been standing for a good amount of time
