I didn't think it was related at all, but at my last OB appt I mentioned that Baby H likes to swim all around at night.... I do feel her here and there in the daytime, but at night she really gets wild!
The nurse said, "Uh oh, that means when she gets here she's going to be up all night..." I don't necessarily believe that, but did the patterns you notice in the womb seem similar once your LO got here?
