hi, I have a question,
my menstration start on May10 and its end on May15,2012. Now, I just wondering why until now July 12 my period not yet come, its almost 1 month.. I used pregnancy test to check it if I am pregnant, I test it 4x in different weeks but the result is always negative.. why its like that? What happen? Am I pregnant even the result of pregnancy test is negative? I hope you answer my question..

thank u..
