Sore boobs before BFP?

My boobs have been sore since my period started and THEY NEVER STOPPED BEING SORE. This isn’t normal because after my period the soreness goes away.

I am 7dpo now and they are much more sore today they hurt when I walk!

Especially when you wake up in the morning and it’s just heavy and omg 😭

Anyone had something similar and went on to get their BFP? 🤞🤞🌈🌈
