Unprotected sex a couple of days before period?

[misfit4leaf.livejournal.com]

A frantic friend of mine wants to know:

She had unprotected sex about two days before the start of her period. She hasn't actually missed a period yet, but I told her I'd ask this fabulous community. The guy never came inside her. What do you think the odds are? I've tried assuring her but she won't listen to me.

Also, though I did not originally choose to address STIs, again, "highly unlikely" doesn't really mean all that much. Carriers, latent symptoms, etc., etc.
