Pink discharge

Carol
This morning I got up to go to the bathroom and when I cleaned myself I found pink discharge, which I assumed it was blood. I got dressed really quickly and my husband started driving me to the ER. Meanwhile, I was calling my doctor which suggested that all they could do was do an ultrasound to see if the baby was ok. I am happy to report that my little bean is well. We got to see it for the first time in 3D with his little arms and legs and it was not only a relieve but a blessing to see that nothing happen to him ( I always say him... Maybe it's a her! Who knows) however, I am still seeing some of this yucky pink discharge again. 
Has anyone gone through something similar?
