My period due was yesterday a week before my due period i missed 2 pills because i forgot my pills at home while we was on a 3 days vacation on my SO parents. But i noticed yesterday that im having like a old blood discharge with a little bit of pink blood on it but not much. Should i consider it as my period? Im not wearing a tampon only panty liners. Is it because i missed the 2 pills thats why im having these very light old blood discharge?
