AF due today or tomorrow.

Briana
I've been holding out on testing because I just hate to get my heart broken. I haven't had many symptoms just that my boobs have been sore throughout my luteal phase but I've noticed the previous cycles when af comes my breast stop hurting about 5 days before. I've had a thick discharge the past few days and feel nauseous on and off but nothing serious. Am I out? Or should I keep hope alive?
