Go to dr?

I’m 33 weeks 3 days. Since 24 weeks I have been having pain under my right rib and on my back on the bottom of my shoulder blade. It comes and goes it’s like a searing burning sometimes stabbing pain sometimes lasting hours or all day. and when I complained of it at my 28 week and 30 week appointment the dr said it was probably my gallbladder or the baby which I really didn’t think it was... but the dr never ran any tests or anything even though I said the pain was severe at times. Well at my 32 week appointment they did an ultrasound to check on the baby and saw my right kidney was severely dilated which may be causing the pain. I got a rental ultrasound done which my dr ordered on Monday (earliest the hospital could schedule me) but still have not heard back the results yet. But I have been experiencing episodes where I can’t catch my breath even when I’m just sitting down and feel like my heart is racing and get nauseous. Also occasionally the last few weeks I’ve been getting bright spots in my vision that only last like 10-20 seconds just bright white small dots floating around. My blood pressure has been fine at my appointments but when I have those episodes of shortness of breath I just feel so miserable. Earlier today I was rolling all around on the couch and my floor I overall just felt so horrible. I’m not sure if it’s just pregnancy stuff and it’s normal and I’m being a baby? This is my second I didn’t experience this with my first but I know every pregnancy is different or if I should try to make an appointment. I have another one next Thursday but I feel like my dr isn’t really listening to me anyway and makes me feel dumb like a hypochondriac..
