Too early for symptoms?

𝙲𝚊

My last period was December 7-11. I woke up this morning with awful nausea that comes & goes in waves. I’ll be okay for a couple hours & then the next thing I know it hits me like a ton of bricks. Hubby and I are TTC baby #2 and I never had any nausea with my first pregnancy so I’m kinda confused about this haha. Isn’t it a bit early for symptoms?
