9 week ultrasounds - look alike - same or different genders?!

Ashely

I have a 1 year old son now & I just went in for my 8 week 5 day ultrasound. Their ultrasound pictures look A LOT alike. Does this mean I’m bound to have a boy again? Praying and hoping for a girl🤞🏼. The bottom picture is of my son and the top is the new baby at 9 weeks 1 day!
