First ultrasound and don't know what to think

Erin

Could use some help if anyone has seen this before...

I Had an ultrasound today for viability because I had some bleeding at 4+ weeks. They saw two sacs - one empty, and one with a baby measuring appropriately and we did see the heart rate was 127 bpm. So it is possible I lost a twin 2 weeks ago? There is also some blood inside so I hope that's not a threat to the baby. I don't feel very reassured with these findings. I'm 6+2 now
