My breasts feel sore?!

My breasts feel sore?

Hello, I am 19 years old, i do not believe I have breast cancer or anything like that but i have a few questions. My breasts have felt really sore recently. I checked out some info on what your breast is made up of, and when i move my fingers around its sore. There are no lumps or anything odd than before, just really sore. I am a size 38 C , could my breasts growing larger produce pain when i squeeze my boob? Or could it be the fact im worried that i squeeze it to much that it becomes sore to squeeze? im not really sure, as much info as possible about womens breasts and signs please. THanks

I'm late on my period, but i've also taken a pregancy test and it came back negative.

~~*~~ There is a gland that runs into our breasts that can cause them be be sore when our hormone levels are high. Our breasts also tend to become swollen with water weight. This can happen when we are a week prior to or on our period or if we are pregnant. It is also common when a new birth control is started or if birth control has not been taken as regularly as usual. Another option is that you are indeed pregnant and you do not have enough of the pregnancy hormone to show on the test. Call your Dr and get another test. You can get help from there. If it is a bra issue, try "sister sizing". By doing that you would wear a 36D instead. (I used to work for a popular lingerie shop.)Good luck!!
