Morning sickness or flu

[Js32313]

I found out I was pregnant about 3 weeks ago. A few days later I got the stomach flu. It was pretty bad. It took about a week to start eating more than crackers. A few days later I got a deep chest cough. Still not 100%. Ever since I had the flu I can't eat like normal. I get a little nausea in the morning. Once I eat I feel better but I don't eat anywhere as much as I used to. When I do eat lunches or dinners it takes me a long time. I get a little nausea when eating also mis this left over from the flu or is this morning sickness? I know it can be any time. I had the flu over two weeks ago just haven't been able to eat like normal since then.
