Small Gestational Sac

Hi everyone!

This is an <a href="https://glowing.com/glow-fertility-program">IVF</a> pregnancy. I went in for my 8 week scan and baby is measuring 7w3d with a heartbeat of 154bpm!

Doctor was happy with these results but subtly mentioned my gestational sac was on the smaller side. She didn’t seem concerned, however google tells me otherwise!

Anyone have an ultrasound that looks similar to mine? Any stories/outcomes are appreciated!
