Been waiting for period...help asap! :/?

Long story short, me and my bf had protected with a condom and it didnt rip and he didnt *** and i was on my period. i started my period around may 28-30 dont remember which day exactly, and now its the 5th so im kinda questioning on why it hasnt come yet. i have always had irregular periods so im not completely freaked out, but the fact that i STILL havent started worries me like what if? and i have sharp pains in my tummy that come and go so i thought maybe it was period cramps? but im not sure what to think or do. what do you all think? am i pregnant or is it coming soon or is something else going on? help please thanks you.(:
