pregnant and bleeding

Jen
I am spotting and it almost feels like a period? I went to the ER and they sent me home again, they said I am either miscarrying or the baby is too small to show? Had this happened to you? Where you bleed but you le baby was still okay? Please help me and thank you! 
Update!!! 
I am in the ER they are saying there is no baby and gave me pain medicine through the iv. They also did an ultrasound but didn't say anything, they will try to see what they find. They are saying I might have an ectopic pregnancy because my levels yesterday's were very high. They also drew more blood. Please pray for me and a soon recovery whatever the outcome maybe.
