Tender breast?!

Hannah
I have had tender breast as soon as I got pregnant it felt like, as well as feeling nauseated. But today my boobs don't really hurt, and I didn't feel sick or anything this morning. This is my first pregnancy, so of course I have a lot of questions... This just kind of scares me and I have to wait 3 more weeks to get my second US. So I hope everything is okay with my little sweet pea. Please tell me this is normal so I can have a little piece of mind!!
