Has anyone lost a twin after 20 weeks?!!

Kimberlee
We found out Friday that our son had stopped growing and that in the last two weeks his heart stopped beating. They have been monitoring him since 19 weeks and they really weren't sure what was going to happen. They think it was his placenta. They told us our little girl is fine and still growing on track and is expected to make it. I am just wondering what to expect. I am currently 22 weeks and 5 days.
