I'm not sure what you are asking.
You're definitely not pregnant sweetie.
You need to relax. Being worried and stressed out will only delay your period further.
You really should consider going ahead and getting put on birth control. This way, if you end up having sex with your boyfriend, you will be protected (fully protected if he's wearing condoms).

There are a lot of reasons your period would be late, and since we all know you aren't pregnant, it's probably due to one of life's stresses. Stress, illness, changes in lifestyle or atmosphere, etc. You're fine. I agree with Marianne0558, you need to relax. If you don't want to get pregnant, don't fool around so much-that just leads to sex. Get on birth control and get some condoms if you want to keep fooling around and be protected. And don't go farther than you're comfortable with.

we arent having sex because neither of us want that.

Even if you aren't having sex now, that doesn't mean you won't later on.
If you go ahead and get birth control, it will regulate your period more and you will be protected in case you all decide you are ready for sex.
I would also get some condoms. It's never a bad idea to keep one in your purse or something, just in case.
You wouldn't want to not have it when you are ready to use it.
