How to get my OB to hear me

How can I get my OB to listen to me? I’m 37w1d and my BP has been on the higher side last night and this morning. I have a massive headache (Tylenol isn’t working) and I’m throwing up most of what I eat and drink. I feel awful. Swelling has came and went for the past 3 days. My OB doesn’t do anything, he does blood work (which takes days to get results) and if it looks okay he doesn’t listen or recommend anything to help. I just feel “off” like something isn’t right. This is my 2nd and last pregnancy so I kinda know what was “normal” last time but I just don’t know how to make him listen to me.. I’m already 37w1d so I’m not switching OB’s or offices.. I just want to know if any of you ladies have had doctors ignore your concerns or what you did? TIA
