Spotting after period

Brook • Mom of 3 girls ages 6, 4 and 2 and another girl on the way!
Just to start out I am seeing a doctor but feel they are not taking my symptoms seriously                               So I have a 29 day cycle bleed for 4 days but then it stops for 3 days and will spot for a week bright red blood only when urinating or having a bm what is this all about? I am not on birth control.
