I am 26 years old and I am hypertensive.I am six weeks pregnant with no real troubles so far.Lately I am encountering a kind of foamy urine whenever I am peeing.I have some swelling in my feet and hands as well.When I told the doctor about my symptoms he said this could be proteinuria.But he wants to conduct a test before he is sure.I want to know the reasons for protein in urine during pregnancy?Should i go for this test or not?
