okay i think your trying to say you had sex sept 19th, she was supposed to get her period on sept 30th, she is still waiting for her period... last pregnancy test oct 13th and negative...

sometimes periods are late or even skip a month for no know reason but its best to talk to a Dr and see what they say, which sounds like she was already there... so i dont think if anyone can tell you any for sure answers... either keep testing every few days or every week which ever she prefers or wait it out and see if it shows next time or go back to the Dr and see if she can get blood work done (including a blood preg test)...
