will i get fired for calling in sick?

I got horrible food poisoning in the middle of the night and at 9 i called the vons store director to cancel my shift that starts at 1. She said i was still in probation (started working there a month ago) and that this will affect my performance. i said well yea but like i have food poisoning.... then she said calling off work is calling off work and implied that i might get fired (dont remember exact words but that was what she implied). it took me pretty long to finally find a job and i really like my job there so i dont want to lose it, but i cant go work i literally can not leave my bathroom.
