Lost/confused

Hi ladies I am 38 weeks pregnant about to pop any minute and I feel like my dr don’t know me as a patient literally I’m in the appointments tops 5 minutes. I don’t even think he knows what my real due date is. He just winging it. I told him my due date was July 6 cause that’s what my first dr had told me...since I conceived through ivf it’s always harder to get an exact date. So July 6 was the date given by my first dr who only saw me 1 time and I think she’s a nurse not even a dr. From there I transferred to my current dr cause my insurance covers this one and not the other one. Anyway he asks me questions like if I had been pregnant before. Like I told you Im verly in there for like 5 min. I don’t even know what my baby’s weight or how long or anything is. And I feel stupid cause a lot of ladies I know say he supposed to tell me this things. And i dont know what the hell is right? I’m a first time mom I just go with what he tells me. Like today I had a drs app and he asked me if I had any contractions I told him well I’m feeling this this and that (tighten stomach pains, pulses under there, back aches) and he said those are not contractions so I was like then what the hell are they. I’m so confused and honestly kinda of scared cause I don’t feel like he takes care of me.
