Is a small bleeding after Escapelle normal or has fertilization occurred?

Menstrual bleeding generally looks like it is more intense at first, then the blood outflow is less, and by the end only spotting persists, which eventually disappears. It is difficult for me to answer whether the Escapelle tablet actually changed anything in the bleeding profile. However, even with this information, it is impossible to determine whether fertilization has occurred or not. The third day of menstruation is generally a day of potentially low fertility or infertility (this depends on the length of the cycle) and before ovulation. In such a situation, the Escapelle tablet should be effective, because it works by blocking or shifting the ovulation during the time.
