8 week ultrasound... Help!!

Gaabriellahh • 27... Baby number 4.. Lilybeau
We had our first prenatal appointment today and it went great. My Beau is measuring slightly smaller( 2 days) than 8weeks 2days based on my LMP. I get that it's a little early to get a good ultrasound picture... Could any ladies help me out in trying to make sense of what is what in these pics?! Thank you
