Seeping... possible tmi

The last 3weeks, at least, my breasts have been really sore; AF did start. But what I am starting to feel concerned about is my nipples have been seeping enough that it wets my bra or shirt. This has never happened to me and don't know what to think... the fluid that comes out is like watery and clear, sometimes has a lil of a cream color. Has anyone else experienced this??
