Vanishing twin

ERIN
After 2.5 years of TTC we got pregnant! Our first ultrasound showed 2 distinct sacs and we were elated! Our second ultrasound at 6 weeks 3 days showed only one visible baby with heartbeat. We had very conflicting emotions! We were super happy for our healthy growing baby but sad for the loss of our other. I had absolutely no signs of miscarriage. Has anyone else dealt with this?!
