Help Me

Okay ! So me and my boyfriend had sex my whole fertile week and even some more after that. I am trying to get pregnant! Am I pregnant? Is it a high chance ? When will I be able to tell that I am ? When should I test ? My period should be here on the 5th which is tomorrow and I have no signs that I'm about to start a period. Normally I would cramp up really bad but I haven't had any of that. Just a lot of pelvic pain and lower back pain ! Help me
