Leaking nipples make you naseous??

I'm 22 weeks pregnant, and a few weeks ago I started leaking clear fluid. Now its turned to a whitish-yellowish color. My concern is that it makes me totally naseous when I see it. Its like the same feeling if I get my blood drawn or get a bad cut or something. I'm afraid my squeemish-ness is going to interfere with breatfeeding. Anyone else have this problem, and do you just get used to it?
