Morning sickness subsidies at 13 week !!

Ok I been very sick from week 7 through 12 it just started to go away 😊 I have no more heart brun but I also took Nexium and they work good . But I haven’t been throwing up or feeling sick like I used to . I mean I’m happy but worried to. I still spit but not as bad as it was . My stomach don’t cramp or have gas pain like it used to. and I can eat a lil more I’m finally going to the bath room at first I was back up and couldn’t go that’s gotten better 😊. Should I be worry or it normal..
