A little insight?

Tonia
So glow had my period starting today but it didnt. Ive had cramps on and off but very, very faint. Anyway, the last couple of days ive been moody and the other day I just started balling and couldnt stop. I was just so frustrated and couldnt see why. So what I needing a little help with is...what the heck is wrong? Could I be pregnant or is it actually a symptom of my periodm:/
