Morning sickness come and go?

Nicole • Married 12/9/17. Henley Nicole made my life complete 11/9/18 💗👶🏻 expecting baby #2 in October 2020!

I had morning sickness badly with my first pregnancy. From week 7-20 pretty much consistently throwing up everyday. I am 6w5d now, and started having morning sickness a week or so ago consistently every day. Now today I woke up and felt fine with only a bit of nausea. I am worried. Can morning sickness come and go?
