OK I been trying to get pregnant I did the online ovulation tracker to see when would be the best time to have sex by going off the first day of my last period which was 9/17/12. I had sex on the 22 of sept. 2012 and I ovulated on the 1st of oct 2012 but I had sex the day after I ovulated I been having symptoms like I'm pregnant but my period should have started back on the 15th of oct. 2012 the thing is it's the 15th and my period have not came on yet so I took two pregnancy test one at home and one at the hospital but both time it said negative what does that mean I'm I pregnant but its to early to tell what should I do can you help me understand what's happening?

It's too early to test yet. You may just be late on your period.

Too close to the date of sex, It will be into the first of Nov before you can really test.
