Did the morning sickness got better from week8? Because my morning sickness was not as bad as week 6, 7. Is that normal?

Hi all, I was having morning sickness for the past 1 week, vomiting for about 3 days. This morning I felt totally normal, like I’m not nauseas, my stomach is less bloated, when hunger came I don’t feel like throwing up. I am only at week 6 or 7, is it normal? I’m worried as I had 2 chemical pregnancy before.
