I'm 20. Um last perion was last month, last week of the month. This month I have not gotten it yet. I have cramping, that feels kinda like period cramping. Been goin on for about 3 days now. On and off. I find myself eating a little more than usual. And for the past few days I've been having lots of *stool*.. but other than that I am completly fine. Could I be pregnant? Or no.
