How Long Does Marijuana Stay In The Body?

Hi, I am getting an epidural injection tomorrow for my lower back. I have a herniated disc. And in a lot of pain, I smoked marijuana yesterday and the place doing the injection told me I need to take a pee test for pregnancy since I m being put to sleep. Will THC show on this test?
