Please help I don't know what to do.

Tabitha

My little girl is 8 months old and I can just tell she is not feeling well. She woke up at 3 in morning screaming crying and she was like that on and off for 2 hours. She has been like this all day. I can't tell if she is just spitting up or throwing up. Its not much but she has been doing it quite often today. She has no fever or any other signs of being sick. I just dont know what I can do to help her feel better.
