Worried about preeclampsia

I went to the hospital yesterday for swelling of my feet/hands/face accompanied by a headache that wouldn’t go away with medication, posterior nose bleed, dizziness, nausea and weird eye sight. My blood pressure was 138/89 and stayed like that the entire 4 hours I was there. My usual blood pressure is about 120/70 ( never had an issue) they ran blood work and everything was ok and no protein in my urine.

Has anyone else had symptoms like these and they stayed and you ended up being diagnosed with preeclampsia? I’m 34+6.

My feet and hands are still swollen, even after elevating them. I’m drinking tons of water like usual. I still feel nauseous, dizzy and have a headache that won’t go away. It all started randomly two nights ago. I’m worried they could have missed something.
