I lost my virginity about two weeks ago. no condom was used. now i found brown discharge on my pad liner. what could that mean ?

Needs to be checked: You have a brown discharge, you need to be checked by gynecologist to rule out any infection including stds and you wait till your next period and if you miss your period, do a pregnancy test in future if you do not want to get pregnant and for prevention of stds till you are familiar with your partner use condoms . Good luck.

Could be pregnancy!: I don't want to worry you, but the brown spotting you are having could be implantation bleeding, i.e., the kind of bleeding women may have in the very early part of pregnancy. If you do not get a period as expected, see your doctor or go to planned parenthood for a pregnancy test. Ask about getting some reliable birth control so you don't have to worry. Good luck.
