Help be my deciding factor!!!

Been ttc over 2yrs now, but have only been using glow app for the last 14months. In those last 14months, I have NEVER gotten past CD28 without AF showing up. Sometimes she'll show a little earlier, but CD28 is the latest I've ever gone. I'm currently on CD30 though, and wondering if I should test now or wait it out a bit longer? Even though I've never been this late before, it's still not SUPER late, & after 26months of ttc, Idk if I can take the disappointment of seeing another bfn. I'm scared outta my mind to test, but do you think now would be a safe time to take one, or should I ere on the side of caution and wait it out a bit longer? THANKS FOR READING & VOTING LADIES!!!
