Bad headache affecting vision 😭

I’m almost 36 weeks and having a bad headache for a few days and now it’s affecting my vision making me feel so off and so dizzy.. every time I call my doctor I have to go through a nurse first and they constantly tell me it’s normal or compare to a family member of theirs that’s been pregnant and I honestly hate calling them anymore 😭 don’t know what is happening or if I should be concerned
