Confused...First ultrasound today.

How did you get your first ultrasound? Was it abdominal or transvaginal? I️ went in assuming I️ was 6weeks and 7days today and my dr did an abdominal ultrasound. He said he couldn’t see much and that my uterus is tilted. He also said I️ may be 5weeks 6days. He suggested I️ go back in two weeks. My last two pregnancies I’ve always gotten transvaginal as my first ultrasound. This time I️ went to a different dr. ☹️
