Could UTI Cause False Positive Pregnancy Test Result?

MY FIRST DAY OF MY LAST MENSTRAL CYCLE WAS NOV 10 2014 AND I'VE TAKEN 2 HPT THAT SHOWED A POSITIVE RESULT FOR EACH. I ENDED UP GOING TO ER FOR STOMACH PAINS AND THEY GAVE ME A 3RD PT WHICH CAME BACK POSITIVE IN ADDITION TO A UTI. CAN A UTI SHOW A FALSE POSITIVE IN PT??? CAN A UTI DELAY A CYCLE???
