Am I Pregnant?!

Hello, I'm New At This And I'm Really Scared That I May Be Pregnant. 
My Last Period Was July 3rd And Lasted To July 10th. I Was Ovulating From The 12th To The 17th Of The Same Month. I Had Sexual Intercorse On The 22nd And We Didn't Use Protection. I Am 8 Days Over Due For My Next Period. And I Have Had Tender Breast Slight Backaches, More Than Usual Urination,  Headaches, And Just This Morning Felt Nausea. I Have Tried A LOT  Of These Apps And I Don't Know Which One Is Accurate. This App Doesn't Offer An Input Date For DOC (Date Of Conception) Just LMP (Last Mentstral Period) And According To This App, I'm 5 Weeks And 2 Days And My Due Date Is April 9, 2013. I'm Not Sure If This Is Accurate Or Not Considering My DOC And LMP. Please Help! It Would Be Greatly Appreciated.
