Postinor 2 is effective in preventing ovulation, if taken within 72 hours of unprotected intercourse and only if ovulation has not already happened.
It should only prevent ovulation once when taken but may cause a delay in ovulation the following month.
There isn't much information out there about taking the pill frequently. I do remember reading that if taken too frequently, as you have done, the effectiveness of the pill decreases.
