Twins- No HB yet?

Rachel
I went through <a href="https://glowing.com/glow-fertility-program">IVF</a> and had my first scan today. I am 5 weeks 6 days pregnant with twins, but neither had a heartbeat... I'm totally freaked out- I had a MC last year where there was a heartbeat at 5 weeks 3 days... Has anyone else had the same experience with a happy outcome?
