It was so confusing

Idk if this will make sense but when i had my first dr appointment my ob said my due date was xmas eve. I went off that date. I had my anatomy scan and she said December 23rd. I kept hearing my dr say that my due date was the 23rd. I eventually said something and my nurse said that when you get your ultrasound THAT determines your official due date so my due date was then December 23rd and no longer xmas eve.

I have been going off November 19th forever and then at my anatomy scan they told me that my doctor had been going off November 21st the whole time even though at my very first appointment he told me November 19th. Doctors are annoying.
