Possible Preeclampsia but no Protein in Urine?

So I now get to do the 24 hr Urine test tomorrow because my blood pressure was 125/90. The dr said cause for concern is top number is 140 or bottom number is 90. I also had an US this morning and amniotic fluid is low and feet, face, hands are swollen. Basically everything is pointing to it except protein in my urine. Has anyone else been diagnosed and also not had protein in their urine?? I’m 36 weeks and she basically told me I’m not going to make it to 40 wks but she is so calm and tells me not to worry. I’ve been monitoring my BP at home and it’s consistently 140/90 or 135/85. So now I’m panicking.
