Bubbles in Urine...Should i be concerned?

Day 33 for me and the past few days, i've noticed bubbles in my urine. Online medical sites say to visit a doctor ASAP, but I'm hoping there's a logical, WF-related explanation to this symptom.

Energy-wise, I'm still pretty lethargic. I woke up this morning w/ a resurgence of that dratted Nausea. I feel like i spent the night eating a 10-pound tub of mayonnaise from Costco. Dark circles are back under my eyes and my face-skin is quite dry no matter how much oil i keep slathering on.

On the up-side, I've learned that the WF can strengthen hair damaged from over-highlighting and it even cleared up some scars I had on my knee.

Here are the panic-inducing sites:
