You may just need a new bra. It may be too small and you need to go up a size or if it is just that one bra then you may need to adjust the straps or the back. Do not keep it on while it is hurting you though. Take it off immediately. It's not good for your breast.
Buy a larger bra and your breasts will stop hurting
This is different for everyone but in my experience, my breasts started hurting right away. I didn't realize it was because I was pregnant until I went to the doctor and they told me I was. They started out hurting a lot when I didn't have a bra on and since then have gotten a lot bigger, harder and still sore with no bra on.
