Just curious about nipple pain pms vs early pregnancy

Just curious if others can share their experiences. I usually get like a dull ache in my breasts before a period, currently 3 days late for my period with 1 very faint positive, but it was a weird looking faint positive so not relying on it just yet.( also think I ovulated late this month)

Anyway, for the past 2-3 days have had very tingly breasts, especially around the nipple area with my nipples going rock hard very often, like every 5-10 mins to the point of being painful sorta thing... and my usually loose bra is fitting mighty well at the moment. I have had 2 kids before and don't remember my breast or symptoms as they were both surprise and birth control babies so was never paying attention to details... have now been struggling for a year this month ttc and just curious of other women's experiences

Just to add, I know these symptoms could mean anything and am not relying on them to answer my question of if this is my month or not, will be waiting a couple more days to test again if af doesn't show before hand. Just genuinely curious and stating my current experiences
