Symptom question

Hi! So I am 7-8 DPO depending on the app. Normally my boobs are super sore before my period but for like a week and a half. So far they have not been sore but today they are SO SORE. And I have to pee like a lot? I have not tested because it’s too early however is that normal for boobs to one day not be sore and the next very sore?
