Morning sickness

Shawn

Can morning sickness start at 4 weeks along? Period is due Sunday and negative tests. I usually don’t get positive till 13-14 dpo. I’m 11 dpo today and have metallic taste and mouth and vomited 2 times 🤢🤮 I may take another test to see🤞🏻🤞🏻 also cleaned up some nasty cat crap! Maybe that made me sick: 🤢🤢
