Morning sickness

As soon as I woke up this morning I have started puking. It has gotten to the point where I’m scared to eat because it come right back up. I’m throwing up all my fluids. Idk what to do nothing stays down not even water. The last couple of times it has been clear water like. I’m at a dead end I don’t want to eat and I’m scared I’m starving my baby. My appointment isn’t until Thursday but ik I’m dehydrated.😩😩
