Should I be worried? Should I call the dr?

My breastfed baby has been spitting up recently. This morning twice she spit up more than a little bit but just now projectile vomited everywhere. Soaked me, her, her blanket, and swing... she has been pooping less recently but she pees all the time. I just don't know what could be wrong. This is my rainbow baby and I'd die if something happened to her
