The Manufacturer states that Plan B does not cover you for sex you have after taking the Pill.
You are not meant to take Plan B more than once in any one menstrual cycle. It's a huge dose of hormone for your body to handle. If you take 2, then there are no studies done on the effects it could have, & at the very least, taking this overdose will cause you a lot of hormonal side effects.
Your best bet would be to get an IUD fitted by a doctor, within 5 days (120 hours) of the unprotected sex. That can hopefully prevent any embryo from implanting into your uterus lining,
