Glow you have forsaken me

So i was looking at my average cycle and i noticed it had me at average 33days off of just one cycle in may, I've been using the app since january where did all my cycles go! Luckily i had a back up and put all my cycles back and well...

It changed my average to 38days, luteal to 16 and says i ovulated on the 15th i believe

Oh and it days my cycle isn't supposed to start until the 1st now unlike the 27th it said before

I'm so confused and don't know what to go off of

I thought my period was starting in 4 days that's why i took an early response and those have been negative, with this new info it says even the best test won't be positive until next week around the 29th

I'm lost

Opinions please
