Unprotected Sex

I recently had unprotected sex on a fertile day according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a>. We did not use a condom & I am not on birth control yet. This has happened before & I have not been pregnant. I still get paranoid & don't plan on having unprotected sex again. I am also getting testing next week. Is everything going to be okay?
