Boobs growing like mad!! Lol

Ok is it just me or are your boobs growing like mad?! I'm 8weeks 2 days and am busting out of my bras already. I have always had bigger boobs and been 'top heavy' as I'm pretty small far with D's but they are sweeling like nobody's business! They don't hurt too bad now (last couple weeks were a killer!) do they keep growing throughout the whole pregnancy or slow down until the milk comes in?? Thanks!!
