trans | excessive breast soreness?

hi ya'll, so i had a question about your experiences when starting breast growth. i'm roughly a month and a half into estrogen (5mg) + spiro (100mg), and while my breasts are growing, they fucking hurt. how normal is this? i was told to expend tenderness & soreness but not actual pain. but this is normal, right? i'm probably being paranoid but it's even uncomfortable to wear a bra right now.
