I'm freaking out!!

I'm 37 and this is my 6th pregnancy. I have always had really easy pregnancies however this one has been rough from the start. I'm 32 weeks along and the nausea and vomiting has not stopped yet ( this is the first time I have experienced nausea). now I am starting to swell up if I sit in one place for to long. it gets to the point that my hands start to turn red and I can't make a fist. the only thing that helps is walking. which brings on the Braxton hicks contractions. all of this I can deal with because i know every pregnancy has it's issues. At my last appointment I noticed that my blood pressure numbers were higher (125 Over 82) then they normally are , but I have really low blood pressure so the nurse said that my blood pressure was normal. on new years day I had to take my 4 year old to the ER (He fell and hit his chin had to get 8 stitches) while I was there with him the ER dr asked if I felt ok because I didn't look well. I told her what was going on and she said I should call my OB first thing in the morning and talk to them about my blood pressure. They tell me to come in and again my blood pressure numbers are higher (132 Over 70). I see the dr and she tells me "this is your 6th you should know the difference between contractions and Braxton hicks. also your urin is still a little so you are dehydrated. you have not dropped yet or started to dilate yet so we will see you in two weeks." I am,so upset she completely ignored my questions about blood pressure and preeclampsia
