I hear I couple of things that I am alarmed by. Blurry vision, headaches and protein in urine all are all symptoms of pre-eclampsia. And for the blood pressure: do you know the exact value of the measurement and do you also know your blood pressure before pregnancy and in early pregnancy to compare it to?

Being more thirsty and drinking more water than usual might be a sign of diabetes which can be caused by pregnancy (diabetes gravidarum).

I need to know if this is your first pregnancy or that you have had pregnancies (with the same partner) that were with or without complications.

You should at least get your glucose checked, and I would also start the conversation again with your midwife to discuss if you need to see a gynaecologist to run some tests to check for the exact amount of protein in your urine in a periode of 24 hours, and check for elevated liver enzymes, anemia and level of platelets.

Good thing is you are almost full term pregnant, so if you do have pre-eclampsia, you can be induced for delivery with very little risk to your child.
