My Abby baby is sick :[

I am worried about Abby, my black lab mix...shes a little over a year now. In January right before we moved I woke up to two very big wet spots...but they didnt smell like pee and she was just laying in them. Well then last month there were little wet spots everytime she was sleeping and they smelled weird..again not like pee..but it was only for a day or two. Well now...she has wet the bed (smells like pee) two nights in a row. The first night it was three little pee spots...and last night it was a big spot on the blanket and a little spot on the sheet. We went to the airport to pick up our neighbor..my best friend here..Nicolette & her adorable baby Makayla...well when we went to the airport we had them in the kennel..and Dustin & Ashley (the people staying with us until their house is ready) said that one of them had thrown up in the kennel. I think it was probably Abby...shes been following me around the house for the last hour or so being super extra snuggly...NOW I know shes not feeling good because whenever Lucas is home I dont exist to her. So I dont know whats wrong with my poor Abby baby. The base vet is closed on the weekend and will be closed tomorrow for memorial day. The phone there is always busy so I walk to there and make an appointment (which is usually impossible to get anyway) on Tuesday...Hopefully I will be able to get an appointment. Poor Abby. :[
