Getting excited.

Kilah
I am now 6 days late. This is really crazy because I haven't been late for a period in over a year,especially not almost a week late. I've had cramps after sex and a little through out this past week which always makes me think I'm about to start my period but to my surprise it never comes. The cramps after sex are more intense than the ones I get through out the day but neither is quite as bad as my period cramps are. My boobs have been sore since the week before I should have started which was the 20th. Is there a chance this is the month? Like I said I'm usually very regular with maybe a 2 day variation some months but never this long.
