Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before.Different experts come online at various times; I just came online, read about your situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner. If you would still like assistance, can you tell me:
Has she appeared to be eating quicker?
Does she tend to do vomit after her morning meal? Or her evening meal?
Has she been eating grass, drooling, gagging, retching, or lip licking at other times?
Has she been drinking more then usual?
Are her gums nice and pink (not white/pale)? Moist or sticky?
If you press on her belly, does she have any tensing, tenderness, discomfort, or pain?
Could she have eaten anything she should not have (ie bones, stones, socks, toys, plants, chemicals, human meds, etc)?
