Your story sounds so similar to my first pregnancy. I reported all my symptoms to my doctor at my 34 week check up, and he had an answer for every one. I had pitting edema (swelling is common in pregnancy), trace protein (nothing to worry about), blood pressure significantly higher than my 90/60 baseline but not over the diagnostic line (nothing to worry about), a headache (probably dehydrated), floaters in my vision (history of migraine), gasping for air even while sitting (the baby's pushing up against my lungs), etc. Each symptom by itself may have been nothing to worry about, but all of them together added up to a giant red flag that my doctor completely ignored. Four days later, I was admitted with severe PE with central nervous system involvement, borderline HELLP syndrome (two of three symptoms, and the third just short of the diagnostic line), and going through an emergency induction. I was transferred by ambulance to a better hospital, and the MFM who took over my care said we should pray the induction worked, because I was so sick a c-section would kill me.
All that to say, you're right to be concerned. PE can get bad fast, so don't feel bad about bothering your doctor even if you just saw him and will see him again in a few days. It's his/her job to make sure you and baby are still okay.
