No sore boobs this pregnancy? Anyone else experience this? I’m freaking out!

Hello, I’m pregnant for the third time and my boobs aren’t sore or tender at all yet. My first was a miscarriage and the second was my now one year old son and both of those pregnancies my boobs were sore almost straight away. I’m only 5 weeks now but they were definitely sore by this stage in the first two pregnancies so I’m getting worried and the dating scan isn’t for a few more weeks. Has anyone else experienced this and had everything turn out fine? And was it a different gender to your first if you did experience this?
