well, I'd be of the opinion that day 14 is day 14, no matter how many days the actual bleeding lasted for.
You count back 14 day from when you'd expect your next period, and on an average cycle length, you'd expect your next period 28 days from the first day of bleeding (not, for example, 3 weeks after the last day of bleeding)
Good to see somebody I remember still on here!!!!
Best of luck on the "home" weekend.
