Breast pain 1st week of pregnancy ?

Okay so before I found out I was pregnant with my daughter the FIRST thing I noticed was my breast pain.

It was so early that I still tested negative on a pregnancy test. Sure enough though a week or so later I got a positive. My boobs rarely ever get sore even for my period.

So yesterday when I was in the shower I noticed the water was hurting my boobs when it was hitting them. I thought... "oh no" 😳

My period isn't supposed to be until 9 days so it's way too early for any sort of breast pain (although I don't really experience any for my period anyhow). I'm almost certain I'm pregnant again because the last time this happened like this I was.

Has anyone else ever experienced breast pain within the first week of pregnancy? And BEFORE getting a positive test? Curious to see other people with similar experiences!
