I was wondering if anyone could help me out, my breasts have been very sore for the last week or so and I'm starting to worry. I'm 16 years old, I wear 34D/DD, and I'm 100% positive I'm not pregnant as I'm a virgin. My breasts are always very sore when I lie down to sleep and I basically have to hold them when I don't have a bra on. I haven't gotten my period since the beginning of June, but being late is actually pretty normal for me. However, my breasts are never sore before my period. I also recently cut way back on my caffein intake, if that's even relevant. Could someone please help me?
