Hi, my medical school requires a drug test for matriculation.

The first test was a negative-dilute because I peed in the morning and then drank more water so that I could actually pee when I was there (I’m pee shy). I understand why this came back as dilute

The second test also came back as a negative dilute despite the fact that I didn’t pee in the morning. I only drank one 500mL bottle at 9:00am and took the test at 12:30pm and I was fairly dehydrated the night before

I have no clue what to do and whether this will cause them to withdraw my offer and I am really stressed. Anyone have any experience with this or guidance? I legitimately don’t do any type of drugs or even drink alcohol. I don’t even know what to tell the school when I reach out
