I always get my periods on time, I'm never ever late. I always get the same symptoms a few days before I start, I'm 22 and for the past 2 yrs my periods and the time they start have always been the same. I either get it on the same day as my previous one or they start a day earlier never later. I should have started on the 15th or 16th and still I haven't started nor do I have any cramps, what I do have is tenderness and I've had it for the past week. On feb 25th 07 my bofriend and I had sex twice. The 1st time we used protection and the sec none and he didn't pull out. I eat normal and excersise like I usually do.

There is a possibility you are pregnant. However, your dates can vary especially with stress.

If you find that you do not get your period within the next 10 days or so, it would be in your best interest to take a HPT using first morning urine.
