Protein in Urine - HELP

Kathleen

Today I went for my 24wks appt and everything was good. At work 3 hours later doctor called they found protein in my urine and they want me to do the 24 hours pee (Has anyone done this) and take the pee to her office and get my blood taken on Monday. I am so scared, should I be worry or what can I do to prevent protein in my urine? Please help cause I am a mess. This is my first pregnancy and I am so stressed about this.
