I'm scared.

Since the beginning of this pregnancy, it seems like nothing can go right. I found out I was pregnant the day I got my IUD removed due to complications. After doing bloodwork to confirm the pregnancy, I was told my progesterone was low. So now I am on progesterone pills, which is going good. Sadly, I started spotting last week on and off. The doctor office was like as long as it doesn't get worse or continues I'm good. Today as I'm getting ready for work, I was spotting still and slightly cramping. I decided to go to the emergency as it was 5/6 in the morning. I sat there for almost 5 hours to be told I have a subchorionic hemorrhage and it was nothing to be done. This is my 2nd pregnancy and I'm trying not to stress but I'm scared. My first child was a breeze. To make it worse I got an ultrasound and didn't even get a chance to see my baby. Any advice or something?
