Nervous

So me and my bf sex back in May and a 2 more times these past few weeks . so my period was supposed to come the 10th but it's 9 days late and I'm freaking out . Every time we did it , it got interrupted by his parents coming home so he never came and to my knowledge the condom never broke either . I have like a white discharge instead of my period right now and I don't know why . i don't get why my period hasn't started yet . this is the first time I've had sex in like 6 months , do you think that could be a reason in delay 🤔
