Sore breasts - 2 weeks before expected period

There’s a chance I could’ve conceived 7/18. My app said my peak ovulation date was 7/21 but I believe I ovulated early this month just by my cervical mucus. My boobs started hurting a few days ago and they feel so heavy and sore. I usually get sore breasts about a week before my period but not this early. I feel like it’s too early for pregnancy symptoms but is it possible to have sore breasts this early due to pregnancy? (I know it could still just be PMS symptoms but want to know if anyone has experienced this and ended up being pregnant).
