1 day late

So I have never in the past year even seen 0 days until period, as I always get it 2 days before the app predicts it. App predicts it was due yesterday so I am literally trying to hard not to get over excited🙈!!! I have taken 2 tests today, both negative but I am staying so hopeful..! I’ve also been experiencing awful headaches for just over a week now (which I have never got before in my life ) so hoping this is a good sign! Fingers crossed for me pleasee!
