Confuse n hurt mother

Hello goodnight I need a little insight if anyone has experience this

I am currently pregnant with twins at 10 weeks. I had a little spotting today and no cramping and I went straight to the emergency room to make sure they were okay.

Ultrasound tech did a vaginal and abdomen check. And the babies heartbeats were not detected.

The doctor explained that it is still to early to detect heartbeats In twins so I should come back in a week time to confirm. Before they know the nex course of action to take
