My boobs feel plum and round after one day of messaging them. does that mean there growing?

hi, i started messaging my breast(boobs) yesterday with oil and today when i woke up my bra felt fuller and when i went yo massage them the felt round and plump but not that firm at all. i'm 16, bra size 36A might have to go up a size not :) do you think it's helping them to grow?
