bad bra?

Marie
I think I have been wearing the wrong size in bras. I have been wearing C to a D cup since like 5th grade. I have gotten back pains, boobs hurting after I take the bra off. Is this normal? Or am I wearing the size or brand? If there is a good cheap brand for a college student that have big boobs and only 5ft please let me know! 🤔😬😁
