Breast feeling weird?

Ok so I know I am probably over analyzing this but my left breast is sore. I would classify it as hurting but it feels like someone punched me on the side of my breast really hard and my nipple is also sore. It's just on the side closer to my armpit. I found this as odd because I've never experienced this before, it's also more sore first thing in the morning. I'm 9 DPO and TTC #1. I know only a pregnancy test can confirm but I was just wondering if anyone else has experienced this and ended up preggo. Just wanted some advice, please no negative things.
