3 weeks post BBL, why does my urine smell?

I am 20 days post BBL. one of the easiest procedures I have ever done. No complications, no problems. I just slept a lot for a few days. Felt so good to catch up on sleep. Anyway, I’m back to my normal routine minus working out and I noticed yesterday my urine smelled so bad. Frequent BMs but not diarrhea. Is this the fat that didn’t survive? This isn’t a UTI, just a terrible smell. I feel totally fine and my personal hygiene has never been an issue! Hoping someone can answer. Thx
