high risk

I'm 37 weeks exactly today & have been experiencing Preeclampsia symptoms for 3 days, but everything my doctor has checked says I don't have it. I've had high blood pressure, dizziness, shortness of breath , headache for 5 days. I went to L&D on Tuesday because I was having contractions that were 5 minutes apart but they discharged me. I am not considered high risk seeing as they have no idea what's wrong with me. Just need some support:(
