Hi Chandlers - I had sore nipples only (rest of boobs were fine) , from 1 to 3dpo according the the notes I put on FF. When I Googled on the Internet, there was this one doctor that kept being quoted (can't remember who) as saying it means no ovulation. Well, I can say that she is wrong - have definitely ovulated according to my temps and my chart has even gone triphasic according to FF.
I did find this comment on the net too from someone who was describing early pregnancy symptoms: "My nipples became quite sensitive 2 days after ovulation, the cervical neck became briefly hard (2 days) at 3 days and the aureolae became smudgy, developed bumps and started to expand at 7 days."
I got this from this site:

Hope this makes you feel better!
Can I have some advice from experienced ladies on early pregnancy symptoms? My burning boobs from yesterday evening, went by this morning crazy when you go ahhh when you get grim SYMPTOMS but miss then when they are gone but have returned this evening, although not as fiery but enough to want to take bra off. A obviously clutching at straws
