I have previously been sexually active but I hadn't been for a month... after exactly two weeks of the last day of my period my boyfriend and I had unprotected sex he came a little bit inside of me... its still to early for me to take a pregnancy test... do you guys think I'm pregnant?

Of course you can be that is what happens when you have unprotected sex

You have put yourself in a very real risk of being pregnant. It probably is too early to test... wait and see if you miss a period by a week or more.

By the way, exactly 2 weeks after your period does not make it 100% certain that you were ovulating. To know your ovulation you would need to look at your cervical fluid and waking temprature for starters.
