Irregular doesn't mean they're all over the place, just that they sometimes come early or late, last longer, etc.; it's still possible to determine your cycle just by paying attention to when your periods usually occur, and if you know that, you also know when you're ovulating.

As for Orihime's birth control, the Enovid pill was first made widely available in the U.S. in 1957, and Margaret Sanger's birth control research started even earlier than that. Illegal and experimental version of the pill were already circulating before then.

It's not incredibly plausible that these could make their way into the hands of a teenage girl in Japan, true, but this is Tokyo; if they were available anywhere in the country, it'd be there. Furthermore, there are all those U.S. servicemen around to boot; since she was whoring, the possibility that one of them gave it to her is fairly likely I'd say.

Not that I'm trying to argue mind you. It's nice to have some discussion up in here for a change.
