Hello I had my period 08/07/12-08-12/12, on 08/14/12 I had unprotected "sex" it wasn't sex because he didn't penetrate me completley it just went in for about 5 seconds first, & then for less then 20 minutes? He never ejaculated and it was just there, but he did have pre both of the tims, is there a possability I'm pregnant please help? Im not on any type of pill or anything?

For 20 minutes??

Maybe even less?

Yes, there's a possibility.

How so? Is it high? According to what I know my high fertility doesn't begin until the 16th?

You can get pregnant at anytime during your cycle, even during your period. "High fertility" pushes up the possibility, but the possibility is always there. And pre-cu'm has sperm in it. All an egg needs is one to fertilize it

Any time you have sex, there is a chance to become pregnant. Unprotected sex increases that chance. The fact that he didn't finish really means nothing... there is still a chance. Perhaps you should learn to be more careful instead of worrying about it after the fact.

At this point, you're just going to have to wait it out and hope like hell for your period next time around.

First you had sex. You were, at least partially undressed and there was penile insertion to some degree. That is sex. ANY time you have penile insertion there is the risk of pregnancy. You will have to see if you get your next period. If it doesn't come when due, wait about 2 weeks to take a test.

Many guys completely finish in 5 or 10 minutes, so 20 minutes is a long time. But 30 seconds is all it takes

There are no way to say 90 percent change, or 80 percent chance, just a chance, too many factors. But yes this is exactly how babies are made
