Diet during pregnancy

Know how you all, that I am pregnant. Today began my 6 week and I felt my first morning sickness. I could not my breakfast food and my beloved Decaf Coffee turned away me. But I still get the rules and to the third phase. I think it is good and healthy for my and my baby. I know I will be weight gain, but I would like to do careful and hierf++r no longer want to use only what is for the baby. I am sure I have some request. Yesterday I had ice but I still think what complies with the rules.
