Could I Be Pregnant?

So I'm not normally one to post to forums, but I'm getting a bit worried. At the beginning of the month my boyfriend and I had unprotected sex, during ovulation. Normally I experience sore breasts, bloating and cramps one week before my period. So far all I have are sore and swollen breasts for over a week now, and my period is two days late. Should I take a test soon or wait to see if my period comes?
