Sore nipples

Rose

I had sore boobs/nipples right before my period normally they go away when my period starts but this period was weird only lasted 4 days normally it's 6/7 days long and it was light and had noticeable discharge normally I don't enough to notice when I'm bleeding and the nipple soreness never went away and I still have it today and period ended yesterday could it mean anything? I'm ttc btw.
