Breast soreness, early symptom?

I'm tcc for about 4months now and not sure if I'm reading too much into this... I have been experiencing breast soreness since the last day of my ovulation which was 4days ago.
I know it's an early symptom of pregnancy but could it be my hormone levels adjusting from recently ovulating? I've also been SUPER moody (my poor husband).
I'm wondering what were some peoples experience with breast pain and pregnancy....or is it pms? I'm not due for AF for 10days. 
I don't want to give my hopes up!
