Ok mamas another question💥

I am going to be 8 weeks tomorrow.

At like Week 6, I have been so naseous and repulsed by food. I threw up the other day cause I got hungry :( Food I normally love makes me nauseous. Well today I didn't feel naseous and my dad made BBQ chicken which I ate (usually ever since I found out I was prego, meat has not been appealing) but today I ate all my meat and rice and even went back for 2nd and thirds. Seems like my nasuea is all gone? Can it happen that fast??
