Please help me!!!

I don't start my menstrual till the 16... and the last week or so I wiped pink one time very small amount... and now my lower stomach has been feeling as if I've done sit ups and some cramping, I really hope it's not Aunt Flo I want this to be my month, but could someone tell me what you think, and the drastic change in my eating habits... I could eat and still be hungry what is going on...

🤞🏼I'm praying it's not AF she isn't due yet and I pray she stays away.
