Sex a week before your period

Hey ladies! So last week my husband and I had sex without any protection... A lot..;) AF was due 10/1 and she hasn't come yet. We just got married, so I'm wondering if she's late because of wedding stress? Or if it's possible I'm pregnant. My fertile time was about 2 1/2 weeks ago, and I know chances are really slim to get pregnant right before your period. I really would love a baby but my husband is hesitant as he wants to enjoy marriage alittle before a baby comes along. Any thoughts? Should I test? Or just wait for AF...
