Dehydration in pregnancy

Ruby

So I have felt faint and sick to my stomach. I usually throw up daily but today I had diarrhea along with throwing up. I dont think I'm sick. I have noticed that my urine has been really yellow almost orange and also realized I havent been drinking much water. I drank 3 cups of water and feel a tad bit better. But still feel crappy, can it just be dehydration? I'm super scared since I am a hypochondriac
