Mine has been dark since about 10 weeks with protein since 14 weeks. Bp goes high with activities. So I'm hoping not pre e. You are at risk since you had it before.
Dehydrated probably. That's typically what dark urine means. I have had protein in my urine on and off this pregnancy. I had my son last year at 37+3 because of hypertension getting so bad and had like 5 24 hour urine test done. I'm 36 weeks today and blood pressure is up and down and leaking protein and my urine is typically about the same color every time regardless of protein in it or not.
