Just need to vent

So I used an app before glow which was literally ALWAYS on point. I was supposed to start AF according to that on the 29th. No signs. No AF. Glow says today. Still no signs. All tests are BFN I am using the dollar tests. Should I get a stick test? Or think I will start AF soon. I hope not. I've had dreams this was my month. I've had so many feelings this was it, and I just had my hopes up. I'm devastated right now.
