Early pregnancy sign - boobs?!?

Missed AF = 1 week / last AF = 03/04/20

Sore nipples for past week

Veins have gotten bigger and colours around nipples changing - is this is a good sign? Only had extremely faint positives to date so can’t go by that just yet

Had spotting (Browne/pink) a while back when wiping (half day of that) only and not had a full bleed
