so last month , i missed my period . instead of having it , it was just brown discharge . i thought maybe it was like that bc i was extremely stressed that month . this month , i had brown discharge on my pad and light pink blood when i wiped the first day and then on the 2nd & 3rd day it was very heavy (which is normal) and now on the 4th day , it has stopped and now it's just brown discharge again . i have not had sex or any sexual relations. help ?
