Anyone else having nipple 'twinges' ?

Rebecca
Hi guys! I'm 5 weeks today and how I knew I was pregnant before I tested is that when I would brush my teeth and gag myself, I get these twinges in both of my nipples!! I've never felt anything like this before and it still reminds me daily that I'm pregnant :) so weird though because everyone I've told has never heard of it before haha. Everyone is different. Anyone else like me out there? :)
