Is my girlfriend pregnant ? urgent

apologises for graphic description: my girlfriend and i had sex 9 days ago with a condom that didn't split or tear or even come off. yesterday when she was aroused, the discharge in her underwear was an odd colour, an orangey brown, i thought this was spotting but it didn't flow naturally like a period, it was in her discharge from arousal. she also reported that blood came out when she went to urinate after penetration, but this may be because we haven't had sex much ever before. Im worried that she's pregnant. her period is due any day now, but is very irregular, although she's reported to have worsened skin, a larger appetite and sore breasts. is she pregnant or was the bloody-dischsfge just a sign of her period coming?
