My period is so far 8 days late:

My circumstances:

-been in a little bit of stress from school but i dont see it more than usual

-i workout at least twice a week

-the last time i had sex was may june ish and ive had a period since then

-ive been thinking it is coming since i randomly cried the other night and craving foods

-we have family histroy of periods stopping and problems with having childern

I dont know if any of those matter, but im concerned and confused as to why its late, what i should do and all?

Thanks
