Brownish Charge

Hi mga mommies! tanong ko lang kung naexperience nyo na din to.. I'm 7 weeks pregnant with my second child.. Nag-do kami ni mister tapos kinabukasan medyo brownish yung v.charge ko,parang lumang dugo. Di naman ganun kadami at wala naman pong masakit sakin or anything. Normal lang kaya yun? Thank you in advance! God bless..
