Okay so I'm 6 days late with my expected period. About 4 days ago I experienced some cramping and was sure I got my period but nothing. I have some signs like unusualy sore breast the constant feeling like my bladder is full but only get a little urine... I took a dollar store pregnancy test both last night and this morning and both were negative. So my question is could I still be pregnant or am I crazy what's going on?

Yes, it is possible. While most women would get a positive result by this time if pregnant, some find it takes quite awhile. It may also be that your cycle is off this month and you will have a late period or skip it altogether. Wait another week and see what happens. If still no period, try another test at that time. If still negative, you could see your doctor or just wait until next month and see if your period shows.
