My both nipple are pain.why?
You may get your peiod soon, Or like 4of7deadlysins said you may be growing , If you have any other symptoms such as feeling sick in the morning, back pains, or not being able to go number 2 then you may be pregnant but its best not to worrie too much about it . Go to the doctor if it gets worse. Hope I helped feel free to fun mail me.
your breasts are probably growing. either that or you'll be on your period soon. it's normal though. but if it does get serious or you're really worried about it you might wanna go to the doctors.
Maybe your about to start your period, or your pregnant. That's the only reasons I can think of.
