Protein in urine

Cinthia • Lost my sweet baby at 36 weeks. I love you Naomi. Forever and ever, you`ll always be my first perfect baby girl. :(
They found protein in my urine and my blood pressure was high. The doctor is concerned so now I'm stressing out, which is bad I know. They did blood work and I have to return Thursday. So far my tests have been normal up until now. Has anyone else had this and what happened?
