Do you think this was negligent of my midwife?

I'm not the type to sue or anything but I was taking my blood pressures and got high readings. Then I'd go in they'd tell me to lay down before they checked it and they got normal 110/70 type readings. The thing was I was getting 150/100 on my own and what was realized when I was put in the hospital is that it was pregnancy induced hypertension and me sitting up or standing it would shoot up to 150/100. If I got up to use the bathroom the bottom number would get close to 110. This had gone on probably 3 weeks before being admitted to hospital bed rest (and I am very active day to day) then being induced early a few days later. I was concerned about my blood pressures and I feel they overlooked them because they didn't want me to have to deliver in a hospital. Neither did I but I think had they listened to me, referred me to an OB and I went on blood pressure meds and bed rest when it first started I could have carried longer. My baby was only 6 weeks premature and perfectly healthy but what if something happened? I would have blamed them. Am I wrong for feeling this way?
