My fiance being pregnant, for some reason has not been able to keep food or even water down for the past 12 hours! Constantly vomiting and cramping, clearly dehydrated. Got here around 4:00am now she finally has a bed, but in the middle of the hallway. I have a feeling from the last 2 times we have been here, they are going to do a trans vaginal ultrasound, I can promise you, she will not be happy. The noise is terrible. A homeless man who sleep talks/screams waited with us for about 2 & 1/2 hours. Screaming, singing and being obnoxious. Worst visit and last
