Opinions about my obgyn

So I think I want to switch obgyns. My problem is I'm already 28 weeks pregnant. I need advice should I just stick it out or look for another?

Reasons why:

I know you shouldn't compare doctors because everyone does things differently but when I was pregnant with my first baby they checked me for dilation/cervix everytime I went in. This time they haven't checked me once. I keep telling them I've been having contractions off and on and lots of pressure down there so I figured they would atleast check once right?

Another thing is every nurse I have met in the office has been kind of rude. In the beginning of my pregnancy I was super sick all the time losing weight etc. So they prescribed me zofran. I could take the pills every 8 hours. I work full time (50 hours plus) as well as have kids at home and so right at 8 hours id take one because I NEEDED them to work and be able to provide for my kids. Well I needed a refill so I called the nurse. She goes how come you need more already? Where did they go? The tone in her voice just made me upset like she was accusing me of something. I explained to her that I literally took them every 8 hours and she asked well do you think you could cut down? Well thankfully by 22 weeks I completely stopped taking them cause they acted like I popping pills. It really hurt my feelings.

About a week ago the office called me and the nurse left her name on my voicemal so i called the officr back she stated I never called you and i said well you left a voicemail with your name? She goes huh must be another nurse?it was odd.

Another time which happened today I went in for my 28 weeks appointment and had a new nurse I've never had before and she goes have you went and got your labs done? I stated I hadn't because I didn't know about any labs that I needed to go for. She just stared at me goes well you need to go get those done because your already 28 weeks.

Am I just being emotional because I'm pregnant or should I look into another obgyn?
