Scan 8w - help

T

Hello everyone.

So I went to my first scan.

From my last period I’ supposed to be 8 weeks, but when I went do scan this doctor (not my regular, because she is in holidays) said I was 5 weeks.

When I google this GS measure, I think it corresponds to 7 weeks.

I’m so frustrated. Can anyone with my time (due 24 march) compare this whit their own and give me some highlights?

Thanks
