Can one cockroach lay eggs in a day?

I just founded a cockroach in my room yesterday , as i was trying to kill it. it got away, I took some pest control sprays and sprayed all the corners of my doors / walls and cracks. The next day i saw it wandering near my couch. I used my slippers can killed it, I've been seeing infos about how cockroachs can lay 100 eggs ! i'm not quite sure if it layed eggs before i killed it. :/ Is it possible for a cockroach to lay eggs in just a day?
