Little white dots areola

I’ve had this little white dots appearing over the last couple days in various spots on my nipple and areola, the middle of my nipple also looks to be white ?? i’m not too sure if this could be sign of pregnancy ? my boyfriend did finish in me twice couples days before ovulation as well as on day of. What are odds of pregnancy ? i took test 7 dpo and was negative, i’m due my period tomorrow. hoping for pregnancy but don’t wanna get my hopes up over nothing. i’ve had on and off nausea as well last couple days, especially when in car, other small things but like i said don’t wanna get hopes up! what do you guys think ??😓

edit : day of period, i now have spotting but only when wiping, it’s a small amount of blood. started at around 530 this morning it’s now 8, could it be implantation bleeding ? i don’t usually spot before periods, never like this. i’m going to see how long the spotting lasts. send baby dust !
