Is it morning sickness ? Or nausea?

Hello beautiful ladies,

From the moment I wake up I am not in the “mood” to eat anything because nothing sounds good, but I eat because I am HUNGRY.

I end up having a little bit of food then feel like “bleghhh.... I don’t want to eat this anymore”

After my meal I’ll get heartburn and just burp my tiny meal.

Is this nausea? Is it morning sickness? This happens to me all day with all my meals?

Mind you— I Have NOT thrown up at all and I am currently 4 weeks and 3 days.
