One-sided breast pain

La

Has anyone ever had breast tenderness on one side related to early pregnancy or PMS? I usually get mild achiness in my boobs before my period, but I have A LOT of tenderness on the outside of my left breast. My right breast is only mildly achy. Last time I was pregnant both boobs felt like daggers, but I don’t remember it starting with just one 🤷🏻‍♀️ I am 8 DPO, and the pain started around 6DPO.
