End to the morning sickness?

I'm 12w2d and my morning sickness is still really bad, lasting all day and sometimes even all night. Just wondering when everyone else noticed the morning sickness subside? My mom experienced morning sickness up until she was in the hospital giving birth. Praying that's not the case for me😕
