What are my chances?

I had my first viability scan yesterday after my first <a href="https://glowing.com/glow-fertility-program">IVF</a> cycle. It showed a 18mm sac with no yolk or embryo. I was supposed to be about 7w6d in. They have recommended that I have another scan in 10-14 days. But the nurse pretty much told me that it does not look good at this stage. So I'm feeling very down right now.
