ER can't find baby at 6 weeks

Ya

I went to the ER last night because I had an orange tinge when I wiped and slight cramping. After doing blood work and two ultrasounds they said they can't see the baby. My cervix is closed and my hcg levels are at 200 I believe. They were so cold and didn't tell me anything else. I didn't even get to see the ultrasound. I'm so scared and don't know what to do or how to feel. They want me to come back in two days to do it all over again. Can anyone tell me what's going on? I'm scared I'm losing the baby and this is my first child too.
