Help, I forgot my cover letter :’(

I apply to a job at a petsmart. They want a resume so I did that and went and sent for my application. And a couple days go by and I completely forgot my cover letter. I look on their website and couldn’t find no email to send one too. I looked on LinkedIn and everything. Oh the website it only mentions a resume. What should I do cause my head is racing. I really wanted this job!!
