Plan B is not as reliable as regular hormonal birth control. It is simply worth a try in the event of an emergency.
If your partner was ovulating/fertile, then you need to use one of the other methods of emergency contraception; either have an IUD fitted into her uterus/womb by a doctor, or get her the other pill, Ulipristal Acetate. Both of those things may be effective if done within 120 hrs/5 days of the unprotected sex. Again, they are not as reliable as regular hormonal birth control.
Most women who have a regular monthly period, are fertile around the middle of their menstrual cycle; around days 10-18, as a rough guide. Ovulation tends to happen in the middle of that time, but cervical mucus changes to preserve sperm it comes into contact with, a few days prior to her ovulation.
Day 1 of her menstrual cycle is the first day of her period.
You may also want to get checked for sexually transmitted diseases, as people can carry those with no symptoms.
