That's still not very precise information about your periods*, but it does at least tell us that not having a period by the 8th (over the last four months) isn't anything out of the ordinary. In other words, it doesn't sound like your period is late right now.
What's probably different this time is just that you're worrying about it because you've had sex now, and from the sounds of things in your other post, aren't super comfortable with it when it comes to things like the possible pregnancy risk it creates. Especially since it sounds like the two birth control methods (condoms and withdrawal) you're using aren't really what you'd prefer, and it also sounds like you have a family who you aren't likely in support of you engaging in sex.
So, I'd suggest you start thinking about what you can do to address, resolve or manage what's got you worrying about your period right now. That's what will probably help you with any stress around this. otherwise, you'll just wait on your period to show up like usual, and in the event it doesn't by the middle of the month or so, then we can talk next steps.
If you want more help addressing or resolving this stuff -- like figuring out if it's really okay with you to be having sex using the limited methods you can right now, or seeing if you can't get some family support, for instance -- we're happy to do that with you in this thread or the other you have going.
* In the future, what's helpful so you and others can have/get more information about your cycles is at least making a note of which day your period starts on so you can have actual dates to share.
