I'm so fed up!!!!

I have gained 9 pounds of fluid in a week… yes 9 pounds in 7 days. My blood pressure is high, I can't say a simple sentence with out running out of breath. I'm so swollen I was at friggin Walmart and a random stranger told me I needed to go get a scooter thing because she has never seen ankles this bad. My back pain is CRAZY like back labor and my midwife doesn't seem to notice… how can any of this be healthy for me or my child?! I'm 37+3 it's not as if I'm super early. I just need advice. Is this normal?
