Morning sickness! :/

Khyrstin • I am happily 👫 with 👧🏼3, 👶🏼19mo, 👼🏼 July 2017, and 🤰🏻due 3/9/20.
I am 7 weeks tomorrow, and am extremely nauseous (for the first time). I thought I was in the clear! Did anyone else start getting morning sickness this late? 
Ps. I'm in grad school and have class all night. Wish me luck!!!!!!!
