Is this normal? What would you recomend?

Today I have been brutally sick. Ive always had bad morning sickness.. Ive been taking diclectin which my doctor has prescribed me for about 3 weeks now. They seemed to be helping, but today is the worst ive been sick. Can't even keep water down, my appetite sucks today i went to the pizza hut buffet.. I loved it before but couldn't even eat.. Had a bite of the apple desert pizza and was done. My energy is also so low. didn't have the best sleep last night but I did get some.

18 y/o I'm 10w today!! And I'm a first time mom. Should I be worried?
