Blood pressure

Is blood pressure alone with no other symptoms something to worry about in pregnancy? I'm 35 weeks and have had high blood pressure spikes and nothing to cause it so I'm curious if that alone is enough to be an issue. I've been to triage many times for it over the past couple months. My first pregnancy I had preeclampsia and I have experienced a couple other symptoms throughout but I'm curious if since blood pressure is my most reoccurring and long standing symptom if that alone is an issue. And if it is what are the risks.
