Worried about dehydration

Hayli • Mama of 3 🎀💙🎀
Hey ladies, my morning sickness has escalated in the past two days to the point where I can't even keep water down. My husband just left on an important family vacation for a week so I'm home alone...at what point should I start getting really worried? My doctors office is SUPER busy, should I call them tomorrow anyway? Or should I just go to the hospital if it keeps going?
