Egg white discharge few days before period?

I'm trying to conceive, I had intercourse on all the days I was suppose too.

My period is suppose to start on the 11-13th according to my app. I pretty positive it will start on the 13th.

Symptoms: cramping in the pelvic area on and off for a good 3 days now, sore / tender breast, woke a few times feeling sick but never gagged or threw up, discharging a lot mainly clear and sticky almost like egg white.

Today when I pressed it together with my fingers and it spread without breaking. What does that mean? Am I ovulating again or fertile or just common period symptom?
