Are you supposed to eat 6 small meals while pregnant?

Meagan • I am happily married to my husband.
I'm 13 weeks and it's hard for me to eat 6 small meals a day. I have "hyperemesis gravidarum as well and I still vomit everyday sometimes and it's hard for to find food that will agree with me. I've been eating fruit salads and I was told to not eat fast food? I really don't know what to eat while pregnant. I just guess mainly.
