Am I pregnant?

I had unprotected sex a few times this month, both been tested and everything and I'm on birth control and my period are always 2-3 weeks apart, never more. It's been 4 weeks and 5 days now. Should I test? I don't want to freak him out. We are both seniors in college, and graduate in 2 weeks and have full time jobs lined up and moving in together once we graduate.
