She's likely to want to molt first (they usually do after having babies) before mating again. So, it could be a bit. But if you keep them together and they do mate, as long as she can't hide away from him for an extended period of time she shouldn't berry. He'll just keep mating with her, replacing his own sperm plug and prevent her from berrying.
I had this happen with my P. clarkii, I couldn't figure out why she wouldn't berry after mating. Turns out all her hiding spots he could get to her in and they just kept mating and mating and mating lol
