first ultrasound!!!! 👶🏽💚💜

So yesterday I went for my very first ultrasound, and it was so exciting and I was glad to hear everything was just fine!!! I am a week behind what the app was calculating, so I am 9 weeks!!  I got pictures and heard heart beat which was a rapid 173 but here are pictures! What you guys think?! I've got told boy because of the side it's on, also because of the heart beat!
