Boob problems

So t minus 9 days until my period. My boobs for the past few days. So i dont think its period symptoms because i get my symptoms 4 days before. They have been unbelievably sore and soooo painful. They grew a lot too. Im not sure if they are just swollen or they acrually grew though. Went from a perfect fit of a 38c to a perfect fit of 38D within like 2 weeks. Also you can now slightly see blueish greenish veins. Any ideas of what could be the problem?
