Hi ladies- Is my chart Triphasic?! Does that mean pregnant ??

Hey lovelies, I'm Haley- Ladies I need some advice, as I'm new & this is my first chart!! ;) 

I'm only 20 years old, no fertility issues in either sides of family. LMP may 18th. Longer than usual- usually only 4 days but i just got off the pill on 5/15. Always have gotten AF on time the next month after stopping it, so Ive never had probs with delayed O!

Ovulation detected by app, but could've been later perhaps? I feel like I O'd when the app says. 

Last hpt was digital FR Gold on the 15th @ 5am- negative, then I peed on it again yesterday just cuz lol, and it turned to YES. I know that's not reliable but I have so many symptoms of pregnancy & my temp is rising. No sign of AF- I'm late by at least a day, could be even a week late but I know she could be off from the pill. :) 

So ladies what do you make of my chart?? Should I test again or wait a few more days?? Does this look like a "triphasic" pregnancy chart? (Not sure what that means.)
