another prob la..most prob is ur breast is lactating, or producing milk, there are many reasons, try consult a gynea doctor, a girl if u scare, go to any nearer hosp to ur house, seek consultation, gov hosp is better, like hukm, hkl, or the newer 1s,
u shud not be lactating, izit ur bf do alot of naughty stuff to u?im seriously asking, he bite it or suck it frequent?
anything can cause it, try a gynae doctor ok?
