are you counting from the first day of your last menstrual cycle? or if your cycle is longer, do you have an idea of when you O'd?

I don't think you need to go in exactly at 9 weeks. I had my dating ultrasound at 6 weeks 5 days!

Said another way, you have completed 8 weeks and you are now in your 9th week. By the end of this week, you will have completed 9 weeks. Generally when people talk about weeks along, they talk about it in the former way, i.e. how many weeks you have completed.!

I believe they count the weeks starting from the first day of the week, so like the others have said, you are done with week 8 and starting week 9.

I was reallllly confused too because if I count the # of weeks based on my last menstrual cycle, I would have been 6 weeks at my previous obgyn appt. Turns out I o'd really late and I was only 4ish weeks along!!

I think the weeks are like your birthday. For example, I'm 28 years old, but I'm in my 29th year of life. When a baby is born, they are in their first year of life, but aren't considered 1 years old yet.

So if you are 8 weeks, you're in your 9th week. (I'm also 8 weeks along and in my 9th week).
