Loss of symptoms?

Kristin • Wife. Puppy mom. Expecting baby #1, due 10/26/2016 👶🏼🍼
Anyone else have a sudden loss of symptoms? I'm 4w 6d and don't see the doctor until March 17th for my 8w ultrasound. I've had cramping, fatigue, increased appetite, heartburn and some breast tenderness. Today I woke up with zero symptoms other than a little fatigue. Should I be worried or is this totally normal?
