If i took bed bugs with me to new house, how soon would they start to infect?

I moved in with my mother-in-law about a month ago because of a bed bug problem in my apartment, so i’m curious that IF i brought any, how soon will they start to show their disgusting selves?? I left ALL my furniture behind and I only brought clothes, shoes, handbags and important papers and pictures…i washed all clothes before bringing it. BUT if i happen to bring one, can you tell me?
