TALK TO ME!!!

Can somebody please tell me some of your early symptoms because Becky (That's what I call my period) is 3 days late and I don't know what to do at this point. I'm constantly hungry usually it takes me 3 hours to become hungry when I first awake and now as soon as I open my eyes I'm very hungry and my stomach is having little wierd cramps and but no sign of Becky and my boobs are really sore!!!😭😭🤒🤒🤕🤕 Any helpful comments about this??
