question ladies ??

So I am 5 weeks & 6 days pregnant and this is my rainbow baby, I have felt a little nauseous , I'll try to throw up but all I do is gag.. my last pregnancy I threw up exactly 5weeks &I I still like meats lol my last pregnancy I couldn't stand it, I hated looking at it , the smell of it & just eating it of course .. I was wondering when I should start having the real morning sickness?? I want to prepare myself as much as I can
