I went to the doctor they did a vaginal ultrasound and measured the baby. At the end they told me I was 9w0d dating on the ultrasound. My lmp was June 2 and they also put it was 9w0d for that. What does it mean?

9 weeks and 0 days.

I mea. Like did I get pregnant EXACTLY 9 weeks and 0 days ago?

It can vary by a couple of weeks. Pregnancy isn't instantaneous, by the way.
