Hello, I m 19 and I ve always have irregular period. This time it is the lingers, almost 3months already since my last period. I thought t was due to excessive exercise cuz recently I played a lot of badminton, I went to the pharmacy and the pharmacy gave me Deviry for 3 days, today is the 9th day since tue past day of deviry but I haven t got my period. I do have some cramps in my lower abs and my breasts are swollen and when I breathe in, my chest hurts, these are the symptoms of period but why hasn t my period come?
