9 weeks and so so sick !

I am 9 weeks and struggling with horrible morning sickness . I can't seem to keep anything down and am not eating well at all. Once a day if I'm lucky and able to keep it down which usually I'm unable . I had to take zofran with my daughter bc of how sick I was . This time around same thing. I just puke up stomach bile bc there is nothing in me. I have no energy and go to the doctor tomorw... they said that it is still ok to take zofran in cases like mine. Is anyone right now taking zofran during pregnancy?
