As she has taken the emergency pill within the stipulated time, she is well protected. As her hormonal
status is bound to get disturbed due to the pill taken twice, she may have her period delayed. The discharge is usually a breakthrough bleed observed after taking the pill. Use of the emergency pill should be restricted to once or twice a year as it has high influence of the hormonal rhythm of the body and this can affect future fertility
. If she does not attain her cycle even two weeks after her due date, she would need a check up with a specialist. Hope this helps.
