Can you do a pregnancy test soon after you have slight bleeding or brown discharge just before periods?

Brown discharge on the 14th day of your period is just the end of your period blood. Stomach gurgling is not a sign of pregnancy and you would have to wait and see if you miss your period before guessing. You actually can only get pregnant the 10-14 days after your period when you ovulate(drop your eggs) and that is a hit or miss thing too.
