hope I'm not the only one ??

So for my period I use the other app eve they offer. It predicted my period to come 3 days ago and still haven't gotten it. Now this app since we are trying to get our baby dance on and get a bfp for a few cycles now is saying af is due tomorrow. Which one do I follow.?? I've also gotten few evap lines and just bfn. Anyone else in the same boat ? Some random light cramps , headaches, nasueous , little backaches, sore boobs but nothing too major that screams period to me. Usally it's like super intense cramping , lower back pain to no end and the brown discharge that is how I know she's on her way. But now it's nothing I'm either dry or creamy almost. I just don't  know and to keep seeing bfn it sucks.  Anyone else out there ?
