Should I trust my gut or my doctors

Ever since I was 30 weeks pregnant (34 now) I’ve gotten horrible abdominal pain. So bad I’ve been in tears unable to walk. It goes across the front of my stomach and down to right where my pelvis starts. It’s a stabbing feeling and definitely not contractions. My doctor said it was round ligament pain and I believed it but it doesn’t go across my sides like my round ligament pain normally does. I just dealt with it tell last week when my sons movement started becoming extremely decreased. He went from moving 30- 50 times a hour and moving my stomach with almost every movment to going 3-4 hours without moving and giving maybe 10-30 movements a hour when he does move (none of which move my stomach or even really show) my abdominal pain has been getting worse since his movements have been decreased to.

Other things that are happening are I feel like I’m about to pass out if I stand up, seeing black dots and losing my vision after I’ve been walking for a couple of minutes, headache, my pee being yellow/orangish no matter how much water I drink, blurred vision and shakiness. And I’m tired no matter what but I think that’s just the 3rd trimester 😂

This is my first pregnancy and my mom says I’m just overreacting and just fine but everyone else I’ve talked to haven’t had these symptoms. I feel crazy. Does anyone have any advice?
