AF due today?

Nicole
So my menstrual cycle was off last month. This app is saying im due for my AF today but i dont feel like its coming, but i also dont feel pregnant either. The only symptom i have is nausea but thats only been yesterday and today. I know thw obvious answer is test and youll know. But i dont wanna get my hopes up. So what are the chances i could get a BFP?
