8 dpo no sore boobs ?

Need some help , I usually have sore boobs before ovulation and up to period I'm about 5 days away from af and no pain whatsoever , couple days ago I've been having off and on pins and needles feeling on nipples sorry tmi , no cramps just minor burrowing feeling on the low right side , I did spot for about a day in a half around when ovulation should take place . But it was pink and red , a year ago around the same time I went trough the same thing with the spotting and was in fact pregnant , at cd 17  Did any of you in fact conceive and not have sore boobs  ? I just don't remember what it feels like :(
