Constant nauseous and vomitting

Week 11 now. Completed the Diclectin about 1 week ago. Have been feeling very nauseous and vomits with or without food since then. About 4 times a day. Taking Dydrogesterone too. Supposed to take it with food. But still taking it even though I haven't been able to eat much. Is that ok? Feeling quite weak now. Next appointment with gynae is 1 week later. Should I wait till then or should I go see a GP first?
