Need it immediately?

So I scratched my pinky finger very small but it bled on my moms screen door which is rusty. I got all freaked out I’ve got anxiety really bad health wise.. I looked @ my booster sheet & I haven’t had my tetanus shot in 12 years & they’re only good for 10!! I’m @ work tonight & don’t get off until 6:30 am & scratched it about an hour ago? I washed it w/ soapy water & put some antibiotic ointment on it & covered it w/ a bandaid but I’m terrified I’m going to get like lock jaw or like get a tetanus infection or something 😭

I’m going to get the booster but I was wondering if I need to get it immediately or if I can get it in the morning??
