plan b?

Tay

So my husband is in the military and he came home on leave this week, and I didn't realize that I was ovulating this week, and he didn't pull out. I took the plan b pill the next day and I read that the plan b pill is basically useless when you're ovulating. does anyone have any experience with this? I just don't know if I can expect the pill to work, or prepare for the worst.
