Resolved Question

I am not on birth control and I recently became sexually active, I used plan-b a couple of times, once in June and once in july. But my period has alway been regular. My last period was September 11th, it lasted until September 14th which is usual. September 16th we had sex, for a couple of seconds before putting on the condom (stupid I know), the condom was old so we stopped, 2 days later I took plan-b but a stronger version, this one is only one pill, just in case. I still have no period, I was suppose to get it october 11th but nothing and we already in the month of november, I already took 8 pregnancy test (I know I am a little obsessive) all of them said negative. The test have been taken at different times of the past month ever since I missed my period. I have no symptoms, I feel perfectly find, but I am still worried I could be pregnant. Could I be??

Please no rude comments, I know this was irresponsible but it already happened so know I need advice.
Thanks

well it is possible unless of course you are male, oh hang on even that has been done, so well yes you are pregnant, why not
