Due date!

Christin

Hey y’all! I ovulated on the 12th of this month and got a positive at 9dpo so I went ahead and booked an appointment. My midwife says I’m 4 weeks and 1 day today! Would that be right even if I conceived on the 12th? She said they go by the first day of your last period! Just wondering if all my apps are right with saying what the baby looks like developing right now! This is baby #2 I just can’t remember how they track weeks because it’s been 5 years lol!
