36 weeks… normal?

I’ve been really dizzy today. When I stand up I get a pounding headache( dull when I’m not standing) and almost like I can’t focus on something if that makes sense? Dizziness is bad when I am moving and walking. Baby’s been very active.I also get heart palpitations. My blood pressure was 133/73 so I don’t think it’s high. My BP was taken by the fancy machines at Walmart by pharmacy.But I’m wondering if these are normal pregnancy symptoms or something to be worried about?
