I am 15 years old and I am not sexually active - I have never had sex. I am two weeks late on my period and the other day I noticed blue veins on my right breast. (The veins may have been there for a while and its possible that I could have only noticed them because I was paranoid) Also, I have been experiencing both sharp and dull pains in my lower abdomen (the very lowest part) and my pelvis. My breasts are not overly sore, nor have they grown, but my lower back has been a little sore and I have been exhausted lately (which could also be because football just started practice and I am a student trainer so I have been outside in the sun for 8 hours a day). I am very scared and nerous about the new happenings, please help! Thanks!
