Sooooooo aggravating !!!!

I’m so very confused. My last period ended on the 26th. As of right now all 3 of my apps have a different window for my ovulation cycle. Now I’m pretty sure it happened the week july2. Which i guess would make me 7DPO. One app says i should be getting my period today. Which is totally incorrect. One app has me at 12DPO telling me to take a test today. Only to see a BFN. And the other one i don’t ever pay attention too. I know i just have to wait for af and find out. But it’s maddening especially since i have no idea where i am at in my cycle. I try to track cm and everything i just feel like it never really changes. Uggh I’m just a big ball of confused anxiousness i just want this to be my month. I hope i am not let down again ):
