Is this morning sickness?

I'm 4+6 and I feel like I'm nauseous all the time. I'm not actually throwing up but the thought of food makes me sick to my stomach and then when I think I'm hungry I'm I eat but then my stomach starts turning. All I have been able to eat for the past few days are everything bagels but even those taste weird now. Is this the beginning of the dreaded morning sickness? I'm not even 5 weeks yet I thought it normally started at 6 weeks

The best way I can describe the feeling is having a hangover and an upset stomach at the same time
