Ovulation

Malyn

So im still new to all this. Has anyone ovulated before the app said your supposed to? Because i think i did! But im not sure but i had bad cramping yesterday and i have 4 days of raw egg white cm. But today there isn't any at all and My temp was in the 97.0 to 97.4 range but today it spiked to 98.0. The app said i am still in my fertile window and im not supposed to ovulate till sunday. So im a little confused. Anyone have any answers maybe
