?Urine color Dark brown?

My Urine at surgery today was dark brown like someone poured a coke in it. They were testing for pregnancy b4 surgery (negative of course) but they never once mentioned the color. I have never had this happen b4. I had a UTI test just a week ago and negative. I have bad left side pain off and on that brings me to the fetal position. My stomach has stayed bloated. It dosen't hurt to pee I do have BV that I have been treating same day I had UTI checked. And it wasn't orange..it was this color⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️
