Pregnancy symptoms

I feel like I’m too early to test but I have had I huge change in my appetite Since Monday I’ve been starving like I’m always hunger wanting to eat. Then I had like cramping, apparently my co workers said I’ve have mood swing really bad and I’m always tired. Idk if this is signs or if it’s hormonal. I have had two apps to trace my ovulation one said last week and the other one said the weekend before. I think last week it was because my discharge was different but I didn’t really check the week before. Is it too soon to test ?
