It'd certainly be unnecessary.But really, that's up to you. Just understand that with a viable risk (and again, I don't think what you described was one), that the sooner EC is taken, the more effective it is. After a couple days, it's chance at being effective is reduced quite a lot, and after 120 hours, it has no chance of working at all.
