[|AI|]  Hi, What pills are you taking to regularize menstrual cycles? Option 72 tablet will not stop your period. It helps in avoiding implantation and thus the chance of pregnancy. It is 95% effective in avoiding pregnancy if taken within 24 hours of unprotected sex. Its effect on menstrual cycle depends on during which part of the cycle you took these pills. If you have taken these pills in the first half of your menstrual cycle, your period may get advanced. If taken in the second half of cycle it may get postponed. However, if your period is delayed by more than a week, then get the pregnancy test done as there is a very small possibility of treatment failure (method failure). I hope I have answered to your satisfaction.
