Ultrasound at 4 weeks?

Nikita

I just got a positive test on friday(8th).

As i called one of the OB/GYN for the appointment, the nurse told me to come today.

Now when i ask about what check ups will be done today, she said we will do both (abdominal& transvaginal) ultrasounds & if needed a blood work too.

I was so confused about the ultrasounds as its way too early?

Please help what should i do?
