Due date wrong?

Question

So I got my positive pregnancy test on.October 25. My last day of ovulation was October 13 and that was the only day out of my whole ovulation week we did the due completely no protection. I scheduled my first ultrasound for November 22. They are telling me my due date is July 4th. I'm so confused about my due date. I tried telling my doctor but they werent listening. They are trying to say I concived on my period. Should I just wait till the ultrasound and not get my panties in a twist or say something to my doctor?

Test taken 0ctober 24, this was 12 dpo.
