question

this is my third pregnancy, although my past two were early miscarriages. lately my breasts have been feeling a lot fuller than usual, tender and sore. but i have a habit of forgetting not to take hot showers, as i normally do. i phones my mom and asked her about why my boobs hurt so bad. i was laying on the couch, rolled over and immediately felt excruciating pain. in my left boob, to the left side, i felt a huge lump. my boyfriend felt it too, and my right boob to the left side (middle of my chest) felt hallow and as if there was nothing there, pained like an internal bruising. my mom told me it was just because the hot water was causing my milk ducts to be very sensitive and hurt more than they should and told me to massage and stop taking hot showers. i’m only 5w3d. is it common to develop milk ducts that early?
