TENDER? SORE? PMS or prego symptom.

I have a question that is annoying me a ton right now lol. Have any of you ladies had swollen nipples before your bfp or once you've found out? My period is due in 3 days and even sleeping facing up & then waking up feels the same as if I was sleeping on them. I lifted my shirt & bam swollen nipples to top it off & it hasn't gone down at Alllllll. 😭 one nipple is darker than the other. Totally throwing me off lol (edd if prego is nov 12). Thank you in advance for any responses! :) *don't plan to test til I'm late, because then I start looking for a line if it comes out negative lol*
