Worried about dr visit and preeclampsia

So I went to the dr yesterday for what I assumed was a UTI- they ended up finding very high traces of protein in my urine and for the first time in my life I had high blood pressure which are signs of preeclampsia- granted I had a hell of a stressful day at work and I'm pretty sure my blood pressure was only high because of stress- now I'm stuck doing a 24 hour urine collection and monitoring my blood pressure every day- I am sure my blood pressure is fine but why else would I have such high protein levels ? Anyone else been having issues? Or worried about preeclampsia? I have to go back to the dr tomorrow and again on Friday- hoping everything works out- im only 26 weeks and now worried about my baby-
