Confused?

Is it normal to not having morning sickness for days at a time? I got it at 6w1d and had it horribly all day long then then 6w2d I only was sick once and was fine for the rest of the day. Now. Today, 6w3d I’ve been completely fine all day? Anyone else have this? I’m sure I’m probably just paranoid but want to be safe 🤷🏼‍♀️
