My period normally lasts between 3-4 days. The week following I'll have a spot here and a spot there but no consistent flow. My period "ended" 3 days ago and this morning when I went pee I happened to glance at the toilet paper after wiping and saw a clump of hair(not pubes). I skipped a period in April, but I had one last month and this month. I took multiple pregnancy tests when I was due for my period in April, I even took one a week ago(the day before this period started)and they were all negative. I even had my doctor test for hgc in my blood at a yearly check up. Also negative. Has anyone passed clumps of hair?
