I am taking the blue Avalo birth control pill, 28 pills. Now I have taken 13 pills, or 13 days, and I have had my period. So pharmacist, can you tell me if I have my period after taking Avalo birth control pill for 13 days, should I continue taking it? Or should I take another pill, pharmacist? The amount of menstrual flow is not much, I only have to use daily sanitary napkins, the menstrual flow is darker!
