What will the ER do?

ka

I’m 19 weeks and started spotting today. We had intercourse this morning. I Called the on call OB and told them, they told me to get to the hospital that they called ahead and let the hospital know we are coming... we got here at 215 and it’s now 305 and we are still sitting in the waiting room. Does anyone know what they will do when we are called back? Like maybe an ultrasound to check the baby and hear the heart beat? I’m freaking out
