I was wondering (not worrying, I swear!) if anyone else has not had any breast changes whatsoever.
My breasts have been a bit sore, and lately the nipples are a tiny bit more sore. But otherwise I have had absolutely no chagnes to my breasts at all. No swelling, no veins, no change in nipples. I get DH to scrutinize them every night (LOL...he enjoys), and he doesn't see any changes either.

Anyone else?

I have had hardly any breast changes, and no soreness whatsoever throughout my pregnancy. They didn't even grow much until well into second tri.

You're quite early on in your pregnancy so watch out - they may explode in the next few weeks!!!!!

Well, this is my forte. With my lst two I had majorly sore breasts. So I figured I would with this pregnancy, and infact they are even worse, but everybody is different hun. Perhaps you are experiencing symptoms that I havent had, and like others have said perhaps you will get more sore as your pregnancy progresses.
Other women at the same stage as us have been physically sick, whereas I have only felt sick.
Some women already have metallic tastes in there mouths and cravings, whereas I havent had any of these things.
Hopefully you wont get the rally sore boobs, but perhaps you will have another symptom hun,

Mine started growing at about 6 weeks and then they settled down.

your only 4 weeks youve got a long time to go before you get major changes to your boobs

I'm 6 weeks and i have no changes in my boobs I'm like you examining my boobs every few hours to see if any things changed but they look the same to me!!!
i have no symptoms what so ever fingers crossed everything's okay just an easy pregnancy!

At your stage, I only had sore boobs.

I've only just got veiny boobs, and I'm 18 weeks.

Alls I had in the 1st tri was sore nipples/tender bbs.

Don't worry.

Not til week 12 for me...Alomost 2nd tri

Mine were sore to start with, then it tapered off and now they're not sore at all. I'm over 11 weeks and they haven't grown noticeably - maybe a teeny bit, but nothing to write home about. My mom positively exploded when she was pg with me, so I'm sure I'm in for a surprise later on
