is it normal for my boobs and nipples to feel sore before i get my period?

the last time i had my period was jan 2 and it ended on jan 8.

i had (protected) sex on the 9th and have been at least once a week the entire month of january.

my boobs and nipples have been sore for the past week, i keep checking my nipples to see if they’ve gotten darker (a possible early pregnancy symptom) but they look the same, just are sore along with my actual boobs

help/feedback is appreciated :)
