the breast pains can simply be that your breasts are growing. My breasts also always hurt before i get my period and during my period.

PM me about all this if you have another ? or are still concerned about anything. You can definitely
PM if you find out that you are pregnant. My sister got pregnant when she was 18 years old (during the summer after she graduated high school) and she has a 1 year old now. so i understand the situation
