we found the heartbeat this morning. The u/s showed an active baby, but there is a pocket of blood in my uterus. They don't know why. It looks like the placenta might not attach well, or at all. They said to expect more blood and go back in 4 weeks to see what the placenta has done. It might be trying to attach over the os; it was unclear. They said the pg is "touch and go" right now.
