If i have blue veins on my breast and ii have aproximately three weeks with a breast pain , am i pregnant? or it could be hormonal changes? im 17

Possible: I you have had unprotected sex, missed your period and are having these symptoms, then you may be pregnant. If this applies, then you should at least get a home pregnancy test kit and see the result. Some people like to get 2 to be sure. If this is not your current situation, then you should see your OB/GYN MD to evaluate your condition. Either way, you should make the appt. and be seen. Good Luck

Check with a test: check your pregnancy status with a home pregnancy test. what you are describing is not necessarely sign of pregnancy. if pregnancy is not on your to do list, and you are sexually active, then practice safe sex, and see a doctor for birth control plan, and enjoy your youth instead of worrying every morning if you are going to wake up pregnant or not. have a better control of you life.and be happy.
