When does weak stomach go away?

Myra • I love my little boy and husband :)

My morning sickness is finally letting up and becoming manageable at 15+2 by that i mean my nausea isnt as bad and constant and I go days without waking up throwing up...but if someone mentions gross stuff that use to not bother me like poop I still gag, smells usually will make me gag till I do throw up 😔 when does this part of morning sickness go away?
