yes mine would always come and go. if your worried dont coz its nothing :)
I am 12 weeks pregnant and my boobs are not as sore but my nipples are really sore and I even get sharp pains at times. But they don't seem to be getting bigger really.. but I am already a D so I think I am good with that one....
well im only 5 weeks 3days and my boobs are only tender here and there so its not a constant thing for me yet so im not really much a help there.. and oddly enof with this pregnancy ive yet to get any morning sickness that ive had with my other pregnancy's but it is normal for things to come and go.
