Irritated with me drs

I'm currently 35w1d and have felt like crap today. Im currently on bed rest for symptoms of pre-eclampsia. Figured I was dehydrated. Was having regular contractions so I called ob and they told me to come in. I get there there took my blood pressure which was 122/80 which is high for me. I'm normally 106/60s. They ran my urine and it was 1.01 they said if it was 1.05 they would start an iv. They just gave me a glass of water and sent me home. On my discharge papers they said if I have any of these symptoms to come back. I said I'm having them now and you're sending me home! So frustrated.
