I just had a baby 3 days ago. I am not breastfeeding and just found hard lump in my breast

During pregnancy, and once baby is born, your body will prepare for breastfeeding even if you don't actually breastfeed. This is likely part of what you are feeling. It can take a little time for postpartum breast changes to occur.


However, if you feel that this is a single lump, in just one breast, best to have your gyn check. Certainly you can have it checked regardless, for the peace of mind.
