AF 25 Days Late and Confused

I am ttc but after being late 12 days I got a bfn and still AF hasn't shown up. I don't have any pregnant symptoms just this extreme hunger pains even after eating a big meal and always super duper tired. When I wake up I have to rush to put something in my stomach bc my stomach starts to make me feel severely hungry and ready to throw up if I wait too long. Is that normal for anyone? Wasn't sure if I should go the doctor for it or not but it started like a week ago. I was really hoping to be pregnant but this strange hunger pain has me all confused. In July this year I had a miscarriaged and now my SO are trying again. Please help me figure out what should be my next move.
