Morning Sickness

Rachel
Hi all! I am wondering what morning sickness is typically like for everyone who's had it. I've has nausea on and off with almost constant diahhrea, and occasional (intense) vomiting. I'm wondering what's normal and what's not! 
​- at how many weeks did it begin? When was it at its worst? 
- how do you feel throughout the day? (E.g., are you normally sick ALL day, or does it come and go?)
​- do you ever get diahhrea also? 
​Thanks!!
