Could I be?

I went to the ER last week thinking I had a bad case of a UTI, they do a urinalysis & randomly ask me if I could be pregnant & asked to check for that, I told them too, well it was a day before my period was expected, well it's been 4 days and no period, my urinalysis came back clean. No UTI & no baby! All he said was unexplainable back& lower abdomen pain!. My question is since it was urinalysis not blood could it have been to early to tell? I did just go off the pill at the beginning of the month, I told them I experienced break through bleeding after I had stoped, so I know it could just be me being irregular, but I'm curious if I should take a test.
