What is the chance of pregnancy after using Escapelle within 7 hours of unprotected intercourse?

I enclose an excerpt from our article that answers your question: "The exact mechanism of action of Escapelle is not known. There are sources that say that it blocks ovulation when it is taken up to 2 days before its occurrence. However, it is believed that it can work not only by inhibiting the release of the egg by the ovaries and preventing the fertilization of the already released egg, but also by stopping the fertilized egg from implanting in the endometrium. Many studies, however, do not confirm this effect, and even indicate the lack of effect of the tablet on the endometrial (endometrial) receptors and its ability to receive the embryo."

And will the pill work even if I took it on the day of ovulation?
