BOOBS Hurt

Good morning ladies.... I'm 17 weeks pregnant with a little girl. I have a daughter that turns five Monday. Any way, for the last two weeks my breast have been leaking kind of clear/milky liquid . I haven't breast feed my daughter in 4 years. Is this normal so soon???? FYI... I also have breast implants. Nothing's wrong with them at all. I will also discuss this with my doctor on Monday. I just need some info
