Will I need a dating US? BFP 13 days late for AF

Tessa

Hey ladies,

Does anyone know if I’ll need a dating ultrasound if I only tested positive at 13 days late for my period? I was testing every 2 days starting the first day I missed AF, but I only got a faint positive by 13 days late.

I’m 8 weeks today but I could be only 6 weeks if I ovulated late. Do you think my OB will give me a dating ultrasound? My first appointment is April 29th at 13.2 weeks (typical where I live in Canada unless you’re high risk).
