Advice please ... Hi I'm 10dpo , I've had brown/pink discharge for the past 4 days . However today I've still had brown discharge also had a little red mixed with clear discharge . I'm not due my period until Sunday . I've had dull cramps and backache . Is this implantation bleeding or my period ? My periods normally quite heavy. However this bleeding is very little I only get it when I wipe it's not enough for a tampon or a pad . Just worried as it has red blood mixed with it as a lot of people have said implantation is only brown or pink . The red blood also has no clots like my period normally does . Is it worth taking a pregnancy test and when should I test ?
