So I had sexual intercourse on 12-10-11 and tomorrow night my friend and I are going bowling she said I should take a pregnancy test because we did not use protection and I was wondering is it to early to take one?

Yes, it's too early, and even if you do take one and it's negative, that is not proof that you aren't pregnant. Are you hoping and planning on pregnancy? If not, chances are that you will get pregnant sooner rather than later.

Of course, you will have to wait till you miss a period and then test.

It usually takes @ least 3 weeks after conseption 4 your body 2 produce enough of the hormone 2 get a positive on a hpt but bowling so soon after really shouldn't do your little 1 ne harm if you do end up pregnant
