Someone please tell me everything will be ok!

Erin • Celebrated 5 years in November. Expecting our first Jelly Bean September 2016 ;)
Sunday night I went to the ER because I was bleeding. It was light pink then it went to dark brown. The ER said you may be miscarrying or maybe not. My levels there were 204. I called the obgyn Monday morning to follow up. They told me to come in that same morning. They checked my levels again. I just got home from having my levels checked again. They gave me the results from Monday (374). The lab lady was like we really won't know anything until these results come back. But my levels going from 204 to 374 in like 15 hours seemed pretty good to me. She said the lab work being done in 2 different labs will make a difference. I have to wait 2 days to get these results back. I haven't had any bleeding since before the hospital Sunday night and no cramps at all. Can someone please tell me this is ok. I am worried sick.
