PMS? Or Early pregnancy?

Allissa

9 days post ovulation (Sex 4 times during fertile window and the day before ovulation)... exhausted.. sore swollen boobs for 5 days now.. increased appetite.. light pinkish/brownish discharge yesterday when I went to the bathroom once, and nothing since then...

My period shouldn't be here til the middle-end of next week..

PMS? Or possible early pregnancy symptoms?
