Sudden discharge?

This may be TMI but I'm a FTM so looking for some relief. I have my next Dr appointment on Monday so I'll be asking then too.
I'm 28+2 today and the last few days I've had a serious increase in discharge, it seems to be normal in color. I just haven't had any discharge the entire pregnancy until now, and it's quite a bit. Is it normal due to increase in hormones or something like that?
