Left boob heavier n hurts more. WHY!!?

ᥫ᭡ Sabiii… • 32 ~ Mum of 1 🌸🤍

It's been almost 3 weeks now that my boobs have been so sore, but its mainly my left one, seems alot heavier more painful and you can see the difference in shape.

Its worrying me a little now, because this has never happened to me before. After a period I'm sure they are suppose to stop hurting but they havent, I've taken pregnancy tests and they are negative so it cant be that..

Has anyone had this???

Or does it look like a trip to the doctors
