Can Delayed Periods, Abdominal Cramps, Fatigue And Bloating Mean Pregnancy?

I had unprotected sex a little over two weeks ago, and I'm almost a week late on my period. I've had small cramps in my lower abdominal area, but they aren't period cramps at all. I've also got a white, milky discharge for the past 4 days, I'm always tired, and I just feel like I'm bloating constantly. Could i be pregnant?
