Sore boobs after ovulation?

About a day after I ovulated (I used ovulation tests) my boobs started hurting SO bad. Like so so sore. It's been 5 days past ovulation and it seems to be getting worse. I'm not due for my period until like a week and a half now (it was like 2 weeks before I'm supposed to start my period when they started hurting). I'm trying to conceive. Could this be a pregnancy sign? I wouldn't think literally the day after ovulation I could show symptoms? Anyone else have had this and found out they were pregnant?
