Nipple pic TMI sorry!!

So I'm kinda convinced I am pregnant. All the symptoms and the last few days my breasts have become a bit itchy and tingly. Tonight my left nipple and around it is itchy and a bit sore. I know it's not a pms symptom as my nipples have never been like this, it also is a bit puffy and look a tiny bit bigger. They're becoming quite veiny aswell which I remember with my first child. But I'm the worst when I'm researching I scare myself way too much. Sorry about the pic but I just wanted to know if other people's nipples went like this when they was pregnant..
