How do I tell him I'm late?

so I had my first time last week, and my period was due about 2 days later and it has yet to come. we used protection and he pulled out but he couldn't get hard at first out of nerves or whatever so he kinda had to jerk off a little and I gave him a blowjob to get it up. and I'm really scared that I may have ripped the condom with my teeth or something or there was a little hole or something even tho he pulled out as he was cumming. and I realize that its extremely unlikely that I could be pregnant but it was a little before my fertile window so I'm really anxious and I also realize that stress will make my period delay even more but I just wanna let him know that I'm a little late because I don't wanna wait til its too late to make a decision between the two of us. or just some advice on what to do for him and my parents cuz I'm really freaking out a little.
