I'm possibly pregnant now, and never get sore
boobs at all in the luteal phase
, and since 1 dpo they have been very achey on the sides, and it's now spread to the nipples. It was really bad like if someone brushed up against me I'd scream, literally! Now, they've calmed down a bit and I have to poke them to feel the pain. With my youngest I clearly remember my chest really aching, like my chest bones and all! If you feel something out of the norm, that's when I'd call it a sign!
