Hi, For The Last Two Days, I've Had A Brownish

Hi, for the last two days, I've had a brownish discharge when I wipe after urinating, and there were what appeared to be a few clots in the urine as well, but I have not yet gotten my period. Are these pre-period symptoms or early pregnancy symptoms? I have a copper IUD, so I don't know if it's really even possible to get pregnant?
