Need advice

On march 26th I had "spotting" it was only pink when I wiped. The next day I had bright red blood but only enough to slightly cover a thin small pad. I had the same pad on all day. that next day it had stopped all together. Not even pink. I normally have super bad cramps but I had literally none this time. I spent Friday in bed bc I threw up and felt like I had the flu. Only to have it gone the next day. Since then my stomach is very queasy. I have no appitite and am smelling things that aren't there. I haven't taken a test yet but could I be pregnant?
