Possibly lost a twin...

Tiffany • Mommy to two boys (4&2)💙💙.Pregnant with with my baby girl 💗 DD:7/3/17. Two angel babies 😇. Married 💕
So Monday I went to dr because I had light bleeding. They said my baby was in my right horn and everything looked great but my left horn was full of blood. Fast forward to last night. I was at work and started pouring blood. Freaked out and went to er. They were able to see my baby in the right horn who has grown since Monday. Monday the baby was measuring 7w4d and last night the baby measured 8 weeks and had a heart beat of 160 💕 so very grateful for that. But they did tell me the left side had an empty sac and blood was still there. They said it's a big possibility I was originally pregnant with twins and have lost one. Which blows me away my ob never mentioned it. The ultrasound tech even showed me the empty sac. Anyways I'm still not in the clear. They said my baby that is viable could very well stay viable but then there is a chance I miscarriage altogether. So just if you think about me if you could all pray for me. I really want my baby to make it. Also still kinda shock that it looked like I was gonna have twins. No one in either families have twins so kinda crazy! Lol. Thanks ladies!
