Brown discharge

Good day. Ask ko lang po kung normal ba yung brown discharge. May nangyari po samin once ng asawa ko, nung April 29, and i supposed to have my menstruation last May 15 pa pero until now wala parin kaya nag-take ako ng pt, and it says positive. Pero may mga lumalabas-labas na brown discharge sa akin. Normal lang po ba to? Thanks.
