Nipples look swollen , breast feel heavy, viens in breast , mood swings , fatigue , could i be pregnant ?

Maybe but it depends: If you have engaged in unprotected sexual activity, then yes, you may be pregnant. Only way to find out is to take pregnancy test if you're 4 weeks past your last menstrual cycle. If test comes back negative, talk to your doc about hormonal contraception. Then make partner wear a condom each & every time to lower risk of stds, too. If test comes back positive, talk to your doc about your options.

Yes.: These symptoms sound familiar. Try home pregnancy test kit.

It depends: According to the information above, you are a 19 year old male, so it would seem rather unlikely. However, if you are actually a female who has had intercourse in recent months then it is quite possible! please also see my comment:.
