Is very frothy/foamy urine normal with a well hydrated pregnancy?

My urine is almost completely clear and I’m going often, but it is very unusually foamy. I have a bunch of health issues and my kidneys have been monitored in the past. Slightly worried it could be something non-pregnancy related.

It has been accompanied by throwing up anything I eat and being overly nauseous for the past few days. I don’t think it’s morning sickness because I’ve never been even close to THIS sick. Also stomach pain and back cramping. Im 12 weeks.
