Should I change doctors ?

So my doctors couldn’t tell if I was pg at 2 weeks, they told me I wasn’t pg even though I took a pg test and it was positive then 3 weeks later I was about to take vaccine to prevent getting COVID but I double checked to see if I was pg and the stick read AGAIN that I was pg, so when I told them at vaccine place, they didn’t allow me to get vaccine, unless a note from doctor. So they took me in right away that day to check if was pg at the doctor and they drew blood from me, and did urine test and was like oh yea your pg, but only weeks then they schedule me for a second visit a week later for my blood results, to make sure I was healthy. They then stick me in a ultrasound room without explaining anything (I was so confused, I thought I was about 3 weeks by then). They put me on a table and start doing an ultrasound and I’m like “omg you can see a baby at 3 weeks?” The doctor laughed me and said no your 6 weeks, and I was so pissed, because I had no idea and she made me feel stupid when just the week before she told me I was only 2 weeks. She didn’t even for warn me I was 6 weeks, she told me while I was hearing the heartbeat, and was like duhh you wouldn’t even hear the heartbeat. And I was just like wow how am I supposed to know that, I’m a new mom, to top it you all told me just last week, I was only 2 weeks. My ultrasound was fast and she just rushed me out of the room, and was annoyed that I was asking questions and was like you need to ask your other doctor these questions and my other doctor never came to see me, just a nurse before I left and scheduled me a whole month later for my ultrasound. Does this sound right ladies ? I need opinions badly, please help? I felt like cow in a cattle auction being shipped from room to room with no real answers and no apologies, and just rudness. I’m so use to my partner being there for me at appointments and standing up for me 😭 when the doctors aren’t the best
