Morning sickness symptoms better (?)

Hi all, I’m currently week 8 day 1 of my first pregnancy. I’ve been having really terrible nausea with no vomiting that last throughout the entire day for the past 2-3 weeks that was super uncomfortable. However since ytd At week 8 I noticed my nausea symptom got better and I don’t experience it? Like a good 80-90% better. My breasts still feel very tender and sore to touch. I read that normally morning sickness symptoms will only improve after first trimester. Which is too early for week 8? Is anyone experiencing the same as me? Or this is normal? Thank you ladies.
