Is this an uti

So for the last three days I've been having pressure wen I pee nd I've had spotting I thought I had a urinary tract infection bt wen I went to the emergency room at 1 o'clock this morning they said I don't have it nd the pregnancy test came back negative I'm still spotting nd I only c it wen I pee. Af is due this Friday could I b pregnant or is it an uti
