... Wednesday? If I had sex on Sunday and again on Wednesday and then took the Plan B pill after having sex on Wednesday. would it work?
You have a maximum of 72 hours to use Plan B, so you may have been too late for it to have been effective for the sex you had on the Sunday.
It's also more likely to work, the sooner you take it.
Plan B works by delaying ovulation until the sperm leaves your body.
If you're already ovulating then it can't do that, & you'd need the other emergency pill, Ulipristal Acetate, or to have an IUD fitted by a doctor. Either of those things can be done within 5 days/120 hours of the unprotected sex.
It therefore depends where you were in your menstrual cycle, as to whether or not it would be of use in preventing pregnancy.
