Super sore nipples for past 4 days

ImPerfectMom • I am who God says I am
Hi all! Hubby and I have been ttc for over 2 years on and off. Have been having Super sore, super sensitive nipples this past week and my period is 4 days overdue. Am I pregnant? 🤔. All info I'm finding points to period symptoms but I haven't had my period and no signs of it coz I usually get cramps 2 days before. Could be nothing but interested in more opinions.
