It would not seen that pregnancy is a possibility with 11 pregnancy tests as they are pretty acurate now. You could have a bacterial infection that is causing an abnormality in your menstrual cycle. Nerves, stress, medication, rapid weight gain or loss, and infection are all causes of an abnormal menstrual cycle so if you have not had a normal cycle since October 14th I would highly advise that you be seen by your physician for a full pelvic examination and bloodwork to help determine the cause for the abnormality in your cycles. If you have been taking tests for over a month and it still shows negative it is very doubtful that pregnancy is the cause.
