 [ Symptoms ] how long does it take methergine to work for a headache [ Disease ] hi look i cant see it but did you take the missed pill the next day on both times if you had done this then things will be ok but normally if you miss one pill its not to bad but doing it twice in one month if you did not back them up as above but then you have had your period you may just have come without egg on your face but you really need to get your act together on bc pill taken same time same place each day so simple good luck
