sore breast after ovulation?? pregnant moms help!?

so every month after I ovulate my breast are so sore and stay that way until AF. last month I tested for ovulation and had an lh surge but this month I didnt test, but when I had my surge last month, it was 2 days earlier than glows prediction. I am now 4dp my predicted ovualtion and my breast still don't hurt. I have a feeling of nausea in my stomach but not to where I feel like I have to....you know....and some burning in my lower back but I always have back pain. we've been ttc for 6 months and I'm starting to get hopeless. Does anyone who's pregnant or have kids had this happen with your breast or I am just getting my hopes up??
