I need to know asap if im prego?

So i had with my boyfriend last wednesday and i was suppose to start my period that week. we've been doing it quiet alot lately. i had cramps, discharge, and were sore. he went in twice with a condom and 2 times after without but he went and cleaned before he went in bare, but he pulled out before he med (and yes i know that doesnt 100% work). last month i started my period on the 28th and i almost always start a week early. now im waiting for my period to come and it still hasnt. i still have all the side effects for your period but its just not starting. im scared im pregnant and yes i do know about birth control and i wont be on it til next month. so what do you think; do you think im pregnant or noo.... and i know im only fifteen years old but please dont hate. i made my choice not yours. thanks!
