Ok me and my girlfriend were 14 and 15 she had her period 2 weeks before we had sex and she was spotting when we did I pulled out I made sure but now she's saying she 2 weeks late? Could she be pregnant? Pleaseeee help were scared!

Sure she could. Are you ready to be a father? First, both of you are too young to be having sex... second, since you thought you were responsible enough to be doing it, then you should have been responsible enough to use some sort of protection. Protection is no guarantee but it's better than pulling out.

So yeah, it's entirely possible that she is pregnant. I hope for your sake and a poor child that would be a result of this that she's not. If you get lucky and she isn't, let this be a lesson to you and start being responsible. If she is... well, say hello to a completely new and not so fun lifestyle!

Are the chances lower than?

If it was halfway between periods and you used no protection, you probably couldn't have timed a conception any better than that. I too hope she's not pregnant, but you did hit the bullseye on this one.

There's really no way to tell what the chances are. Pulling out is a ridiculous and not very reliable method.

You're going to have to wait it out until she gets her period or a pregnancy test.

Does spotting make it any different?

You picked about the best time of the month to have sex, so it is almost like you were trying to be pregnant, so the odds are more in favor of pregnancy.

She needs to do a pregnancy test, using the first urine of the morning.

Spotting makes no difference. Since she is late for a period, she should try a pregnancy test. Be sure to remind her to follow the directions on the test carefully.

Stop having sex. That is the only way you won't risk an unplanned pregnancy. A pregnancy can be risky for her health at this age, neither of you are in a position financially, emotionally, or physically to raise a child. Stop thinking of your sexual impulses and be smart about it.
Even with reliable birth control pregnancy can, and does, happen. No method is 100% effective.

Hopefully this will be nothing more than a major lesson.

You should have thought about the possibilities of pregnancy before you dropped your pants.ANY time there is penile insertion there is the risk of pregnancy. If it scared you, then it may have prevented you from making a mistake that may change your lives radically. No one should engage in sexual intercourse until they are financially, physically and emotionally ready to have a child. You fail on all three.

But there is nothing you can do know but get her a home pregnancy test and have her carefully follow the instructions on doing the test. For the sake of this possible child, I hope it comes out negative. And I hope you will keep it in your pants in the future.
