Missed periods and a negative result

Patient: Can i be pregnant, if i missed my period on the 16th of ocober 2014, and still pending? i have a neg result every two weeks since i missed. i have only some light cramps at night. The possibilty is possible due to condom ripping at the end of september 2014.

Symptoms: Light lower abdominal cramps mostly at night. missed period, mood swings
